Did Palmer die after getting hit by that truck?

[Jiro]

I'm pretty sure the only ShinRa executive to die was ol' King Scumbag himself. The rest of the ShinRa folk always managed to survive, so I wouldn't be surprised if he ended up living in Rocket Town, nursed back to health by some old lady who loved feeding him lard.

Scarlet and Heidigger both die when you destroy the prod clod. Hojo also dies after you fight against him as well.

No more horse laughing I hated Hojo and Scarlet though, they were dicks.

Palmer is one of my favourite ShinRa execs because he's in charge of the space program. Space is obviously important. Imagine the Mako energy you could rip out of random planets!
