Flew Qantas Sydney - Singapore - Saigon and Saigon - Darwin - Sydney on the return. Wondered if we were ever going to get off the ground on the take off at Saigon, being intimately familiar with the airport the toes were beginning to curl and much white knuckle clutching of arm rests. Were supposed to fly direct to Sydney but explanation for the lack of direct and the long take off was the amount of goodies we troops were carrying. Impressive demonstration of a short field landing of the 707 in Darwin though. The trip to Saigon was Captained by the then youngest (mid 20's) 707 airline skipper if I recall.
Flew PanAm 707 to and from Hong Kong on R & R. Well used aircraft, elderly cabin staff and a very impressive falling out of the sky approach from overhead (20,000 feet) at Da Nang.
