Southbound your 1226 post makes perfect sense. Your 1326 post shows a lack of understanding.
The first take-off at 0800 does not happen to coincide with the guys getting off their bikes at the sheds (does for some, not all).
An 0800 start time means that:
The night shift put the jets to bed at 2300-0100 or later.
The Ops Assistant opens Ops at 0500, ditto sqn. Cooks and bottle washers have been at it since 0500 too and start breakfasts at 0600. Engineers ready jets and range them on the flight line by 0700. Crews arrive at 0600. Brief and walk at 0715 or so. ATC manned by 0730. and so on.
Put simply a large number of people are at work up to 3 hours or more before start work. As large a number at at work after cease work.
I believe that aircrews are also discouraged from undertaking strenuous exercise before flying.
So, what I want to see is how it is planned for everyone to undertake these three periods of exercise per week. Will the regular jockstrappers be exempt or will they have to do team exercise too?
