Thanks to RedGuy I now know the meaning of the word "flame-bait".
I did not say ALL 121 operators and crews operate in compliance with this definition, though I would wager most do. Every working pilot reading this thread, myself included, is probably well aware that many operations exist that have the pilots on-call 24/7. That's the point of this thread!
It doesn't matter how many other operations are violating the law besides yours. If you went into court and argued that you thought it was okay to speed because the other guy was doing it, do you think the judge would buy it? On-call is not rest!
Prove me wrong, or go haunt some other thread!
