R101 would generate favourable publicity for the airship programme. The final trial flight of R101 was originally scheduled for 26 September 1930, but high winds delayed the move from the shed until 1 October. That evening, R101 slipped the mast for its only trial flight before setting off for India. This lasted 16 hours 51 minutes and was undertaken under near-ideal weather conditions; because of the failure of the oil cooler in one engine, it was not possible to carry out full speed trials. The flight was curtailed because of the need to prepare the airship for the flight to India.
Alfred Pippard of the R100 and R101 airships. The public enquiry into the latter's crash, which ended British participation in airship development, found no faults with Pippard's work but he withdrew from the field of aeronautical engineering – feeling keenly the loss of several of his friends amongst the 48 dead. During the Second World War Pippard was a member of the Civil Defence Research Committee which met at Princes Risborough and continued his teaching at Imperial College. Pippard was a member of the council of the Institution of Civil Engineers for fifteen years and was their president for the 1958-9 session.
