Spinning larger aircraft
The Indian Airforce back in day one spun the Bristol Freighter, and wrote back to the manufacturer asking for correct spin recovery technique!
2:
A B747(Classic) did a one turn spin when the crew failed to observe an Autothrottle disengage, and the bird slowed up in Alt Hold untill too late it auto rotated.
They used the gear to control the huge speed excursion on recovery, lost the gear doors and limped into LAX.
The aircraft was flown home (orient) about a year later after Mr Boeing did one or two repairs.
The crew Paxed home with out expenses or a future in aviation.
