Last minute checks
I reckon my theories on doing a walk-round JUST BEFORE take off, and certainly after all ground handling people & vehicles are clear, is common sense and should be factored into the timetable...
A rather good example being the INSIDE wheel fractures posted here recently by an observant Captain on his walkround.
I don't know his name, but would happily fly with him in anything, anywhere - whereas I as a photographer have been led to ask ex- Lightning pilots,( not Dunsfold ) in a light aircraft throttling up for take off, " err, aren't we supposed to have 3 not 2 greens ?"!
