OH NO!!! They flew 11hrs! The worlds going to end! Please, I fly that much fairly regularly when returning on a 91 leg, heck I've flown as much as 15hrs in a day. The 125 company I used to work for could fly for 16hrs a day and often flew more than that if returning on a 91 leg. 135 is allowed 10hrs with 2 pilots I don't see why 121 should be any less.
