It's my understanding that from the time of collision to the time that help arrived, 47 minutes transpired. This is unacceptable. Were they not being tracked by air traffic control? Wouldn't the controller have seen there signal disappear? Graham's an ass.
They would have been in an exercise area and as they were exercising for air shows they would have been performing at low altitude.
But a snowbird team is a nine aircraft formation and the leader of the formation would have been in contact with Moose Jaw.
The practice would be for an aircraft to remain over the crash site until rescue could establish its location and start to respond, Possibly, fuel permitting, an aircraft would have remained until a chopper arrived.
But then I am an old fart and things might have changed over the years.
