For those who watched the horror of the 9/11 events unfold on live TV it illustrated that nothing is seemingly off the agenda as far as terrorist shock, audacity and surprise is concerned. Truly stranger than fiction.
However, if there was a plot to do something wicked with the MAS aircraft, and that MAY have been the case, the world will have known about this by now.
So..... as a poster said many many posts back - the aircraft and its passengers have perished,the aircraft sank to the sea-bed somewhere and will eventually be discovered.
Thats ALL we know.
