Hi,
Lemurian
Secondly, when you understand the physics phenomenon involved in the fuel leak, then you can talk to me. Until then, you're just making smelly puffs of air.
It's really a pity that the time has researchs were conduct to minimize the risks caused by leaking fuel tanks you was not part of the experts party.
Apparently because the experts at the time don't understand the physics phenomenom involved in fuel leaks they were unable to predict the coming catastrophe .. and so they called it a unprecedented event.
Or .. they knowed all about .. but cause design they were unable to correct the problem unless drastic modifications and involving a big amount of money ?
