Has anyone ever departed the East coast at night and flown for close to 24 hours?
How did they feel landing the aircraft in the dark, windy and rainy London weather after a circa 24 hour duty?
JFK I was told had a 3 hour tempo a few days ago with the usual Summer CBs.
What if it’s turbulent during your rest breaks and the seat belt sign is off/on. It’s not uncommon and you can’t sleep.
As the wise gentleman from the Fire Dept made comment doing long shifts. They get rest in a proper bed at sea level that’s not subject to noise/turbulence or low humidity.
Too many assumptions made and no like for like science or data.
