My bigger fear is something like the Russian jetliner blown up by a soda can bomb.
If they are mass-produced and convincingly sealed, and each includes a digital date-time watch detonator, any number of jihadists could just be told, “Be in an airplane or someplace crowded on the 4th of July at noon GMT” or whenever they are set to all explode.
My guess is the plane brought down over the Med was also a victim of a soda-can bomb.
I have a gut feeling an attack is going to happen in a major US airport within 48 hours, like at SFO. Or MCO. Breeching the front desk areas, well before the security areas. Its the pattern.
