Well said TS, an anonymous phone call and the "hanger's & floggers" are out in force. IF it IS true, instead of the anon call, why not a knock on the door and a quiet reminder like " Uh, ain't you guys flying sometime soon"? In the event of being ignored or balled out let them know they're just a phone call away from the brown stuff.
In the meantime, benefit of the reasonable doubt eh?
