Melbourne to Toronto 14 years ago (via Sydney and Vancouver), ~28 hours all up. I was withdrawing from nicotine and couldn't sleep a wink. It was a torture I wouldn't wish on anyone.
Flying from Bali to Sumbawa about 20 years ago as a kid. 12 seater airplane. Takeoff was held up for half an hour while the pilot unscrewed the panels containing wiring behind all the cockpit controls etc and tinkered around in there for a while , which was in plain view😬
