Yes, that it was a template date was evident! But I think it's normal to append a specific date to any report.

Relieved to have confirmation that no one died on the ground, thanks.

Good point, A Squared.



Do they predate the CV-340? Presumably not. Is the aircraft only refuelled over-wing, or does it have a refuelling gallery for pressure refuelling?
