So, does that mean if my UK issued JAA licence expires at 23:59:59s on the 14th, I am still OK to fly in the US, say Seattle with an 8 hour time difference,on the 14th at 17:00 local time?
There doesn't appear to be a definitive answer. I'm guessing that it wouldn't be valid but that's just a guess.
Cheers
