3 Stooges Plot Foiled on Way to L.A.?

Ok, I'm just trying to picture how we stopped the bad guys from using shoe bombs on an airplane on its way to L.A. Let's see, did these bumblers think they would:

1. Pound on the cabin door with their feet until their shoes exploded?
2. Take off their shoes and pound the door, with the same result?
3. Take off their shoes, place them in front of the door, light them, and go running back down the aisle holding their ears?
4. Take off the shoes in their seats and ask passengers next to them to borrow a small knife or nail clippers so they could construct the explosives?

I'm at a loss to understand the credibility of this story, how about you?
