It would take more than 10 minutes to crash due to bad fuel. Poof, two gone in four minutes. No mayday. Bombs. Or, as some wags here suggest, two simultaneous center fuel tank explosions ;-).
I actually would not be surprised if this is actually just ONE airplane down.
I need some education.
Are planes refueled from a common source or does each carrier have it's own fuel storage at an airport?
If it is from a common source would there not be more than 2 planes affected? Lastly, how difficult would it be to sabotage the storage tanks (not speculating, just curious)
