Flaps.
Long ago, we had a new Captain on the 'ole L1011 at SV who decided it was a good idea, having just received an ATC instruction to cross ElDaba at a later time, decide that flaps/slats at FL330 was a good idea.
Opps.
They extended alright....at M.75
One slat section was torn off straightaway, and one more departed on the diversion to Cairo.
He was sacked.
No altitude restriction was listed in the AFM, however...it did say max Mach number, .50.
Guess he failed to read that part...
