You lot should be made to fly the Smith's flight system before being allowed on those pretty electric aircraft!
Talking of electric aircraft and back CRS's, a close pal left his Brit and wandered over to look at my newish 1-11. We were sitting up front when the subject of Back CRS came up. Absolutely dead-pan, I told him that since it was such a rare occurrence these days, the FD 108 couldn't do it . . . But, if it was urgent, we could press the nob hard in and release the instruments, pass them across the flight deck, and plug 'em in.
It was at that moment we were interrupted.
A year or so later I was greeted with 'You Bas
!!!!!!!!!!' When he'd finished spitting nails, he gave a cringing laugh and told me what happened.
Collins flight system course, and in a quiet moment he'd told them he already knew how to do the back-beam. It was when the entire course was staring at him that he realized. He hasn't forgotten.
