Shows how ineffective the FAA is as it has until recently refused to enforce this regulation, endangering countless lives with exhausted flightcrew members at the controls, due to commercial pressure from airlines! Finally the old proviso "circumstances beyond control of the certificate holder" is dead which previously "allowed" pilots to not have had a legal rest period in the preceeding 24 hours...hope PanAm gets the crap fined out of them...maybe some flight department managers should go to jail..
