during the show "Ghost planes" that aired on H2 on 9/3/2014 it was said that radar info had shown that during the flight ofMH370 its altitude had went from an approximate height of 24,000 to 45,000 and then back down again. if this is supposedly true can anyoneout there tell me how quickly this occured ? was it within the capabilities of the aircraft? im sure anyone reading this can guess where im going with this. thanks to anyone out there for your help.
