One direct result was that pilots would henceforth never use the words 'take-off' until ATC had cleared them for take-off.
A sound concept. We adopted it as an SOP immediately on the RAF VC10K fleet - but then along came some pompous Sqn Ldr ('Thrombo' - the wandering clot, for those who remember him) who said that it didn't correspond with the official wording in the RAF publications of the day ("C/S, Request take-off"), so we should continue to use the old wording - even though it was less safe.
Fortunately no-one paid any attention to the fool.
