... does appear that a violent sink-rate developed from about 50ft - but surely the aircraft should be able to withstand this?
An early post mentioned that, the investigation revealed records showing that the airframe had had two previous hard landings and these had not been properly examined. Consequently, this landing was too much for it and the gear gave way, being thrust up through the wing rupturing cables and lines. Inevitably the No3 pod struck the ground but it was, in reality, already over by then and only a question of how the airframe would react to the natural forces unleashed by the failure of the right main gear. I sit to be corrected.
