Runway Hazard At Singapore Airport. These Daily Telegraph exclusive pictures help to explain the accident to the B.O.A.C. Constellation, with the loss of 33 lives, at Kallang Airport, Singapore, on March 13. The top photograph shows the end of the runway, on the left, and the top of the sea wall, on the right, painted with light and dark strips. The grass slope between them is only about 15ft wide. The ridge at the end of the runway is also visible. The lower photograph was taken from the direction of the sea wall looking down the runway. It shows the point where the wheels on one under carriage leg hit the ridge. The round object, a runway lamp in a concrete casing, seems to constitute in additional hazard. December 02, 1954.
