Really. So you’re going to open a door on a 777 in mid flight, AND, manually throw out 230 bodies. Sure, piece of cake.
No, not a piece of cake. And preferable to do with a number of hijackers, rather than one. But doable? Sure - here's how:
1) Cut or break the top half off of a meals cart.
2) Roll each body onto the cart, roll it to a door and dump it off. make a pile of bodies at each door.
3) Slow down the plane to just above stall.
4) Rope up, open the doors one at a time, and kick out the piled up bodies with your feet.
