Correct me if Im wrong.. but cant a brick size (1lb or so) totally pulverize a bus/truck, large vehicle?
WTF 150lbs?!
IIRC, shoebomber Reid had approximately 4 ounces in each of his shoes. So, half-a-pound could do signficant damage to an airliner.
At that rate, this amount could create 300 pairs of shoebombs.
And those explosive sheets could do all kinds of damage to unsuspecting persons.
