Kai Tak Airport


Kai Tak Airport was the international airport of Hong Kong from 1925 until 1998. Officially known as Hong Kong International Airport from 1954 to 6 July 1998, it is often referred to as Hong Kong International Airport, Kai Tak, or simply Kai Tak and Kai Tak International Airport, to distinguish it from its successor, which is often referred to as Chek Lap Kok International Airport, located at the islands of Chek Lap Kok and Lam Chau, located to the west.
Because of the geography of the area positioning the airport with water on all sides of the runway, with Kowloon City's residential apartment complexes and 2000+ft mountains to the north-east of the airport, aircraft could not fly over the mountains and quickly drop in for a final. Instead, aircraft had to fly above Victoria Harbour and Kowloon City, passing north of Mong Kok's Bishop Hill. After passing Bishop Hill, pilots would see Checkerboard Hill with a large red and white checkerboard pattern. Once the pattern was sighted and identified, aircraft made a low-altitude 47° right-hand turn, ending with a short final and touchdown. For pilots, this airport was technically demanding, as the approach could not be flown by aircraft instruments, but rather visually because of the right-hand turn required. The History Channel program Most Extreme Airports ranked it as the 6th most dangerous airport in the world.
The airport was home to Hong Kong's international carrier Cathay Pacific, as well as regional carrier Dragonair, freight airline Air Hong Kong and Hong Kong Airways. The airport was also home to the former RAF Kai Tak.

Geographic environment

Kai Tak was located on the east side of Kowloon Bay in Kowloon, Hong Kong. The area is surrounded by rugged mountains. Less than to the north and northeast of the former runway 13 threshold is a range of hills reaching an elevation of. To the east of the former 31 threshold, the hills are less than away. Immediately to the south of the airport is Victoria Harbour, and farther south is Hong Kong Island with hills up to.
When Kai Tak closed, there was only one runway in use, numbered 13/31 and oriented southeast–northwest. The runway was made by reclaiming land from the harbour and was extended several times after its initial construction. The runway was long when the airport closed, and when it was opened. This runway opened in 1958 and operated until the closure of the airport. Beforehand, in the period of 1945-1955 the airport used a different 13/31 alongside a crossing 07/25. These runways were and.
At the northern end of the runway at closure, buildings rose up to six stories just across a major multi-lane arterial road. The other three sides of the runway were surrounded by Victoria Harbour. The low-altitude turning manoeuvre before the shortened final approach was so close to these buildings that passengers could spot television sets in the apartments: "...as the plane banked sharply to the right for landing... the people watching television in the nearby apartments seemed an unsettling arms length away."

History

1925 to 1930s

The story of Kai Tak started in 1912 when two businessmen Ho Kai and Au Tak formed the Kai Tak Investment Company to reclaim land in Kowloon for development. The land was acquired by the government for use as an airfield after the business plan failed.
In 1924, Harry Abbott opened The Abbott School of Aviation on that piece of land. Soon, it became a small grass strip runway airport for the RAF and several flying clubs which, over time, grew to include the Hong Kong Flying Club, the Far East Flying Training School, and the Aero Club of Hong Kong, which exist today as an amalgamation known as the Hong Kong Aviation Club. In 1928, a concrete slipway was built for seaplanes that used the adjoining Kowloon Bay. The first control tower and hangar at Kai Tak were built in 1935. In 1936, the first domestic airline in Hong Kong was established.

World War II

Hong Kong fell into the hands of the Japanese in 1941 during World War II. In 1942, the Japanese army expanded Kai Tak, using many Allied prisoner-of-war labourers, building two concrete runways, 13/31 and 07/25. Numerous POW diary entries exist recalling the gruelling work and long hours working on building Kai Tak. During the process, the historic wall of the Kowloon Walled City and the tall Sung Wong Toi, a memorial for the last Song dynasty emperor, were destroyed for materials. A 2001 Environmental Study recommended that a new memorial be erected for the Sung Wong Toi rock and other remnants of the Kowloon area before Kai Tak.

1945 to 1970s

From September 1945 to August 1946 the airport was a Royal Navy shore base, "HMS Nabcatcher", the name previously attached to a Mobile Naval Air Base for the Fleet Air Arm. On 1 April 1947, a Royal Naval Air Station, HMS Flycatcher, was commissioned there.
A plan to turn Kai Tak into a modern airport was released in 1954. By 1957 runway 13/31 had been extended to, while runway 7/25 remained long; night operations were not allowed. Bristol Britannia 102s took over BOAC's London-Tokyo flights in summer 1957 and were the largest airliners scheduled to the old airport. In 1958 the new NW/SE runway extending into Kowloon Bay was completed by land reclamation. The passenger terminal was completed in 1962. The runway was extended in the mid-1970s to, the final length. This extension was completed in June 1974, but the full length of the runway was not in use until 31 December 1975, as construction of the new Airport Tunnel had kept the northwestern end of the runway closed.
In 1955 Kai Tak Airport featured in the film The Night My Number Came Up.
An Instrument Landing System was installed in 1974 to aid landing on runway 13. Use of the airport under adverse conditions was greatly increased.
In the 1970s an aircraft crash called attention to the potential loss of life in the high-density residential developments around the airport, though there were no serious accidents.

Overcrowding in the 1980s and 1990s

The growth of Hong Kong also put a strain on the airport's capacity. Its usage was close to, and for some time exceeded, the designed capacity. The airport was designed to handle 24 million passengers per year, but in 1996, Kai Tak handled 29.5 million passengers, plus 1.56 million tonnes of freight, making it the third busiest airport in the world in terms of international passenger traffic, and busiest in terms of international cargo throughput. Moreover, clearance requirements for aircraft takeoffs and landings made it necessary to limit the height of buildings that could be built in Kowloon. While Kai Tak was initially located far away from residential areas, the expansion of both residential areas and the airport resulted in Kai Tak being close to residential areas. This caused serious noise and engine pollution for nearby residents and put height restrictions, which were removed after Kai Tak closed. A night curfew from 11:30 pm to 6:30 am in the early morning also hindered operations.
As a result, in the late 1980s, the Hong Kong Government began searching for alternative locations for a new airport in Hong Kong to replace the aging airport. After deliberating on a number of locations, including the south side of Hong Kong Island, the government decided to build the airport on the island of Chek Lap Kok off Lantau Island. The new airport is located far away from Hong Kong's main residential areas, conducive to minimising the dangers of a major crash and also reducing the nuisance of noise pollution. A huge number of resources were mobilised to build this new airport, part of the ten programmes in Hong Kong's Airport Core Programme.
The Regal Meridien Hong Kong Airport Hotel, linked to the passenger terminal by a footbridge spanning Prince Edward Road, opened on 19 July 1982. This was Hong Kong's first airport hotel, and comprised 380 rooms including 47 suites. As of 2018 the hotel still exists, but the footbridge has been demolished. It is one of the few remaining buildings related to Kai Tak Airport.

Closure and legacy of Kai Tak Airport

The new airport officially opened on 6 July 1998 to replace the functions of the Kai Tak Airport. All of the essential airport supplies and vehicles that were left in the old airport for operation were transported to Chek Lap Kok in one early morning with a single massive move, with a police escort.
On 6 July 1998 at 01:28, after the last aircraft departed for Chek Lap Kok, Kai Tak was finally retired as an airport. The final flights were:
A small ceremony celebrating the end of the airport was held inside the control tower after the last flight took off. Richard Siegel, then-director of civil aviation, gave a brief speech ending with the words "Goodbye Kai Tak, and Thank you.", before dimming the lights briefly and then turning them off.
After the last plane, a Cathay Pacific A340-300, took off from Kai Tak International Airport to the new Hong Kong International Airport at 01:28 HKT, Kai Tak was closed, transferring its ICAO and IATA airport codes to the replacement airport at Chek Lap Kok.
Government reports later revealed that Chek Lap Kok airport was not completely ready to be opened to the public despite trial runs held. Water supply and sewers were not installed completely. Telephones were installed, but the lines were not connected. The baggage system did not undergo extensive troubleshooting and passenger baggage as well as cargo, much of which was perishable, were lost. The government decided to temporarily reactivate Kai Tak's cargo terminal to minimise the damage caused by a software bug in the new airport's cargo handling system. During this period, the airport was given temporary ICAO code VHHX.
The passenger terminal later housed government offices, automobile dealerships and showrooms, a go-kart racecourse, a bowling alley, a snooker hall, a golf range and other recreational facilities. In the mid 2000s, the passenger terminal and hangars were demolished. Many aviation enthusiasts were upset at the demise of Kai Tak because of the unique runway 13 approach. As private aviation was no longer allowed at Chek Lap Kok, some enthusiasts had lobbied to keep about of the Kai Tak runway for general aviation, but the suggestion was rejected as the Government had planned to build a new cruise terminal at Kai Tak.
The Hong Kong stop of Celine Dion's Let's Talk About Love World Tour was held on the airport's runway on 25 January 1999.
Until its retirement in 2018, the name Kai Tak was one of the names used in the lists of tropical cyclone names in the northwest Pacific Ocean. Submitted by Hong Kong, it was used four times.

Operations

Terminals and facilities

The Kai Tak airport consisted of a linear passenger terminal building with a car park attached at the rear. There were eight boarding gates attached to the terminal building.
A freight terminal was located on the south side of the east apron and diagonally from the passenger terminal building.
Due to the limited space, the fuel tank farm was located between the passenger terminal and HAECO maintenance facilities.

Companies based at Kai Tak

Several airlines were based at Kai Tak:
Other tenants included:
The landing approach for planes using runway 13 at Kai Tak was considered spectacular and was infamous, not just amongst aviation enthusiasts but amongst the general public as well. Flight sim charts, which are based on the real charts used on the airport, give an outline on the procedures used on approach into Kai Tak Airport.

Checkerboard approach

The Checkerboard Approach initially begins to the south-west of the airport, heading 270 at a minimum altitude of 6000 ft. At this beginning stage of the approach, the aircraft should be passing above Cheung Chau - a small island just off Lantau Island. After that, the aircraft was required to proceed up to "Point Golf", which was on the south side of Lantau Island and directly south of the current Chek Lap Kok Airport. Approaching aircraft then had to make a right-hand U-turn in order to intercept the localiser for the Runway 13 IGS, which generally happened above the current Chek Lap Kok Airport site. The IGS was, in essence, a heavily modified ILS system designed uniquely for Kai Tak Airport, otherwise functioning identical to a normal ILS. At roughly ~2500 ft, the autopilot was disconnected, and the rest of the approach was flown manually. The aircraft then descended below 1000 ft and shortly afterwards reached Kowloon Tsai Park and its small hill. Upon reaching the small hill above Kowloon Tsai Park, which was painted with a large "aviation orange" and white checkerboard , used as a visual reference point on the final approach, the pilot needed to make a 47° visual right turn to line up with the runway and complete the final leg. The aircraft would be just from touchdown, at a height of less than when the turn was made. Typically the plane would enter the final right turn at a height of about and exit it at a height of to line up with the runway. That demanding manoeuvre became known in the aviation community as the "Hong Kong Turn" or the "Checkerboard Turn". For many airline passengers on planes approaching and landing on Runway 13 at Kai Tak Airport, it became referred to as the "Kai Tak Heart Attack", because they were often frightened to be turning at such a close proximity to the ground, which, at less than 150 ft, or 45 metres, was generally less than even the Boeing 767's wingspan, which is considered a medium-size airliner. The turn was so low that passengers could see television sets running in people's residences near the airport.
Handling the runway 13 approach was difficult enough with normal crosswinds because, even if the wind direction was constant, it was changing relative to the aircraft as the plane made the 47° visual right turn, meaning that what would be a headwind heading directly east on the IGS would become a crosswind and begin to push the aircraft over and off the runway alignment without correction. The landing would become even more challenging when crosswinds from the north-east were strong and gusty during typhoons. The mountain range north-east of the airport also made the wind vary greatly in both speed and direction. Watching large aircraft banking at low altitudes and taking big crab angles during their final approaches was popular with plane spotters. Despite the difficulty, the runway 13 approach was used most of the time due to the prevailing wind direction in Hong Kong.
Because of the turn required during final approach, ILS was not available for runway 13 and landings had to follow a visual approach. This made the approach unusable in low visibility conditions.

Stonecutters' Approach

Alongside the Chequerboard approach, there was a lesser known approach into Kai Tak that led aircraft over the Stonecutters' DME at a heading of 040 and led into a ~90° turn to line up on Runway 13. This approach was used extremely infrequently, since the Chequerboard approach had a localiser and glide slope to work off of, and DMEs are very rarely used in commercial aviation today. It generally can be assumed this approach was used when the localiser and glide slope were offline for maintenance.

Runway 13 departure

Runway 13 was the preferred departure runway for heavy aircraft due to the clear departure path, opposite that of the runway 31 departure. Heavy aircraft on departure using runway 13 would often need nearly the entire length of the runway, particularly during summer days due to the air temperature.

Runway 31 approach

Runway 31 approaches and landings were similar to other airports in which ILS was available. Runways 13 and 31 are, in fact, the same physical runway, however if a flight is landing on Runway 13 that means that the aircraft is flying in on a south-easterly direction, while a flight landing on Runway 31 would be coming in a north-westerly direction. This applies for flights taking off on runways 13 and 31 - a flight departing from runway 13 would be heading south-east, and vice versa. This is because runways are named for their magnetic heading in decadegrees, which means that a runway oriented anywhere between 125° and 134° magnetic would be numbered 13, and vice versa. The path towards the runway passed within 300 metres to the north of Heng Fa Chuen on Hong Kong Island.

Runway 31 departure

When lined up for takeoff on runway 31, a range of hills including Beacon Hill would be right in front of the aircraft. The aircraft had to make a sharp 65-degree left turn soon after takeoff to avoid the hills. If a runway change occurred due to wind change from runway 13 departures to runway 31 departures, planes that were loaded to maximum payload for runway 13 departures had to return to the terminal to offload some goods to provide enough climbing clearance over buildings during a runway 31 departure.

Private aviation

The Hong Kong Aviation Club formerly held most of its activities at Kai Tak, where it had hangars and other facilities.
The club moved most of its aircraft to Shek Kong Airfield in 1994 after the hours for general aviation at Kai Tak were sharply reduced, to two hours per morning, as of 1 July that year. Kai Tak closed to fixed-wing traffic in 1998. The club ended its helicopter activities at Kai Tak on 9 July 2017. The Kai Tak location, which it was able to use all days of the week, meant that helicopter training took less time compared to fixed-wing training, as usage at Shek Kong is restricted to weekends.

Incidents and accidents

Many planes crashed at Kai Tak due to poor weather and hard approach:

2002 blueprint

In October 1998, the Government drafted a plan for the Kai Tak Airport site, involving the reclamation of of land. After receiving many objections, the Government scaled down the reclamation to in June 1999. The Territorial Development Department commenced a new study on the development of the area in November 1999, entitled "Feasibility Studies on the Revised Southeast Kowloon Development Plan", and a new public consultation exercise was conducted in May 2000, resulting in the land reclamation being further scaled down to. The new plans based on the feasibility studies were passed by the chief executive in July 2002.
There were plans for the site of Kai Tak to be used for housing development, which was once projected to house around 240,000–340,000 residents. Due to calls from the public to protect the harbour and participate more deeply in future town planning, the scale and plan of the project were yet to be decided. There were also plans for a railway station and maintenance centre in the proposed plan for the Sha Tin to Central Link.
There were also proposals to dredge the runway to form several islands for housing, to build a terminal capable of accommodating cruise ships the size of Queen Mary 2, and more recently, to house the Hong Kong Sports Institute, as well as several stadiums, in the case that the institute was forced to move so that the equestrian events of the 2008 Summer Olympics could be held at its present site in Sha Tin.
On 9 January 2004, the Court of Final Appeal ruled that no reclamation plan for Victoria Harbour could be introduced unless it passed an "overriding public interest" test. Subsequently, the Government abandoned these plans.

Kai Tak Planning Review

The Government set up a "Kai Tak Planning Review" in July 2004 for further public consultation. A number of plans were presented.

June 2006 blueprint

A new plan for the redevelopment of Kai Tak was issued by the government in June 2006. Under these proposals, hotels would be scattered throughout the site, and flats aimed at housing 86,000 new residents were proposed.
Other features of the plan included two cruise terminals and a large stadium.

October 2006 blueprint

The Planning Department unveiled a major reworking of its plans for the old Kai Tak airport site on 17 October 2006, containing "a basket of small measures designed to answer a bevy of concerns raised by the public". The revised blueprint will also extend several "green corridors" from the main central park into the surrounding neighbourhoods of Kowloon City, Kowloon Bay and Ma Tau Kok.
The following features are proposed in the revised plan:
The following are major changes:
The government has promised that:
The new bridge proposed by the government, joining the planned hotel district at the end of the runway with Kwun Tong, could be a potential source of controversy. Under the Protection of the Harbour Ordinance, no harbour reclamation can take place unless the Government can demonstrate to the courts an "overriding public need".
The new Kai Tak blueprint was presented to the Legislative Council on 24 October 2006 after review by the Town Planning Board.

2011 onwards

In 2011, with most of the former Kai Tak area still abandoned, ideas were floated to develop the area for commercial property, citing shortages of office space and rising property costs. In June 2013, the Kai Tak Cruise Terminal was opened on the tip of the former runway. Two public housing estates opened on the northeast area of the site in 2013, providing over 13,000 new rental flats. As of 2018, the public estates have been joined by some private residential developments, now nearing completion.
A small park and new hospital have also opened.
A new Mass Transit Railway station, Kai Tak, opened on the former airport land in early 2020. Another station, Sung Wong Toi, is nearing completion.
