The USAF do enjoy their verbigalizationisms; 'Before starting checklist' etc.
However, on every flight (mission) one has to write-out the bold face checklists - all of them - in toto - exactly as printed in the FRCs. Abbreviations and all.
The number of dots between challenge and response may be amended to equal the Sqn number; I pity those on the 918th!
I don't know what the 'Ovrd & Airstart Sw' is, but I know it's supposed to moved to '... ... Ovrd & Airstart'.
Aye
