Things have changed a little since the '70s.
A National Air Cargo Boeing 747-400 freighter on behalf of US Mobility Command, registration N949CA performing cargo flight N8-102 from Bagram (Afghanistan) to Dubai Al Maktoum (United Arab Emirates) with 7 crew and cargo consisting of 5 military vehicles, has crashed shortly after takeoff
An on board oxygen bottle has never exploded on a passenger jet in mid-air, until last Friday.
It is said that pilots are the first one’s at the scene of a crash. Some are caught unaware but most fight the problem all the way down.
