What happened
The aircraft departed RAF Talbenny en route to RAF Northolt. The flight carried a total of fifteen individuals: six crew members and nine passengers. All persons on board were Czech nationals traveling to London for the purpose of celebrating Czech National Day.
During the final approach phase, at an altitude estimated between 400 and 600 feet, the pilot initiated a steep left turn. This maneuver caused the airplane to stall. The aircraft subsequently crashed near Ruislip Station, coming to rest less than two kilometers short of the runway threshold. Upon impact with several houses, the airframe exploded.
The accident resulted in 21 fatalities. All fifteen occupants perished, and six people on the ground were also killed. Among the civilian casualties were four children.
