But my biggest gripe is with the nuclear explosion at the end and his escape from it. Ok so they try and explain it with the autopilot and stuff, but you see him still flying the Bat with five seconds to go and earlier they say the nuke has a blast radius of six miles. Even with autopilot how the fuck did he get six miles away from the blast in five seconds? Its impossible. Also what about the fallout and stuff? The nuke clearly didn't detonate underwater or anything, you see a huge mushroom cloud, so are they saying that the blast didn't effect Batman or Gotham at all? Urgh.
I don't remember the bit where he was flying it with 5 seconds to go, but I'm sure you're right and if so, that's a bit of a flaw I agree. But your point about the fallout: This was a nuclear
fusion bomb, not a nuclear
fission bomb (like current nuclear bombs), and nuclear fusion doesn't have involve radioactive materials. So there is no fallout of radiation. At least, that's my understanding of it.
