Just saw a report here in California that suggests that some significant flight training must have gone into the attacks it appears that the transponders were turned off by these bastards. Judging by the effectiveness of the attacks it is likely that they did some time in a sim, there can not be huge number of facilities worldwide providing sim time in heavy jets, let us hope that this is where the authorities can pick up the trail back to those behind this MURDEROUS act and let them feel the Wrath of America.
