My primary military job was munitions.  One specific I do know for fact is the C-4 demolition charges aka "plastic explosives" are VERY stable.  You can mold it into any shape just like Bill Murray did in Caddyshack.  You can 100% light it on fire and it will burn with no detonation.  It takes heat AND pressure to initiate the explosive detonation. I don't know what happened on 9/11, all I know that I watched it unfold live on TV from shortly after the first impact at the WTC.  There were a LOT of changing stories, eye witness interviews that day and in the days/weeks after.  My gut was that something was waaaaaaay off and I noticed that eyewitnesses accounts stating anything other than what the narrative dictated, vanished into thin air. In the follow on, there have been numerous "accidents" involving many of the witnesses.  The one burning matter for me is that there has never been  closure or disclosure.  Too many anomalies, easily verifiable lies and contradictory evidence.
