Thx again guys.
Yeah, I'd be a complete basket case as a FDX/UPS pilot. Reason being, 1) I absolutely CANNOT sleep on a plane no matter how comfy the seat/bunk is, and b) I have many problems trying to sleep when not on my body clock.
The combination of those two factors have made my limited time flying Europe trips, ahem, interesting. I think my record for going with no sleep is around 58hrs.
Hence my current schedule of only MIA-Caibbean trips with 3 on, 3 off. Life is good.
