Ricochet's- We already have that. Drop a 1000K bomb from a couple hundred feet (going fast so it defuses) and see what happens. I learned the hard way.
Fuel Fire- Again we already have that. B-24. Nuff Said
Gear drop- Great idea but in the video I'm willing to bet the pilot dropped it to lose speed or in prep for emergency landing. IIRC hydraulic systems are separate.
Are these all serious answers?
Ricochets are easy, do it like the video. You shoot a building, bullets ricochet all around, no where did I mention a bomb.
Fuel Fire: read my request again. I mention external drop tanks. You shoot a external tank that someone forgot to drop, it set on fire or explodes. Nuff Said.
Gear drop: very doubtful that the pilot droped the gear to lower speed in prep for a emergency landing. Especially when he is getting his

to him. Hydraulic systems lower and raise the gear, you shot the system in the right place, it releases the up locks and the gear free falls to the down position, which is exactly what happens in the video. Even the speed of the gear drop backs this up.
