OH: USAAF, 1944), p.178 (hereafter referred to as USAAF). The higher the altitude of an airfield, the softer the surface of its runway, and/or the heavier the B-29, the longer its runway had to be for the aircraft to take off. Kai Tak was at sea level, but its runway was soft-surfaced for much of the war.
37 The B-29 runways that were constructed in India and China were 8,500 feet (2,591 metres) long and hard-surfaced. See Keith Wheeler and the editors of Time-Life Books, Bombers Over Japan (Alexandria, VA: Time-Life Books, 1982), p.99.

The Japanese apparently had a scheme to extend one of Kai Tak's runways to about 5,580 feet (1,700 metres), which still didn't allow much latitude for B-29 operations.

44 According to temperature data available for the three most recent years before the war in Hong Kong (1937-1939), early morning (1-5 AM) temperatures began to approach 75°F by late April, and didn't dip well below this figure until mid- to late November. See HKRO, Meteorological Results, 1937, 1938, and 1939 (Hong Kong: Government Printers, 1938, 1939, and 1940) for hourly temperature readings for each day of the year.
