There were still some passenger routes using the 707 in 1982 despite having 8 DC-10 by then.
I remember turning one round at Gatwick. It had come in from Lusaka and then went to Tripoli and back.
I was a liney mech and only signed for oil, tyre pressures and a basic walkround.
When it arrived from Lusaka one engine needed 10 quarts of oil so I contacted maintrol and they said it was allowed 1 qt. per hour and as the inbound flight was 10+ hours it was OK.
I sent it out to Tripoli and was still on shift when it returned about 7 hours later.
The Flight Engineer was not happy. He had topped up with about 20 qts on the turn round in Tripoli and shut it down at the top of climb due to low level. They re-started it for the approach at Gatwick.
Maintrol's response was that we got the flight flown and it will go in the hangar tonight for an engine change.
