well as big as they are.. they are pretty much a nightmare. i was at work the other day, and i happend to see one take off and watched a wheel fall off from about 50 ft.. everytime one takes off.. they send a street sweeper down the runways to look for something that falls off of them. that crew.. was just lucky... im not sure if they have countermeasures or not.. im only a c-130 guy.
