At the same time as the airport, a pair of gasoline/propane car bombs were ignited outside a night club in the UK, Londonistan I believe.
If they are put together correctly, they can be very dangerous. Of course, no “helpful hints” for improvement should be given here.
BTW wasn’t there suppose to be an invader demonstration in Time square yesterday?
Would it be wrong for me to suggest that pristine, straight-from-the-store propane tanks work best? It really screws up the kaboom when you get that vacuum installed, and then ruing the vacuum...
