Wha...bang, WHA...bang
Seem to remember reading a story back in the '80's (air clues?) about an F4 tootling along in BFG land.
Nav drops pencil, loosens straps, curses mildly, and ducks down to retrieve pencil...
Pilot hears nav's cussing, becomes alarmed because nav NEVER cusses, looks in mirror, no Nav, pulls yellow n black.
Pencil retrieved, Nav notices loud noise, seens no pilot, and pulls yellow n black.
The conversation on the way down must have been priceless as the Toom carried on perfectly serviceable but a tad lighter.
