Amazing . . .
When Kirk ejected out of the saucer in the Kelvin pod and looked down at the saucer hundreds of feet below, the pod's trajectory came dead-on from the section of the bridge where it should have come from. The new Star Trek movies have the bridge on B Deck as opposed to the usual A Deck. This does solve quite a few issues, including rapid escape.
Also, that would take away a lot of the danger of staying with the saucer as it plunged in to impact with the surface, as was seen in Generations.
They should have dropped the Kelvin pods with mannequins from a leased cargo plane above B.C. and filmed it. It may have been too expensive and time consuming but would have added a lot to the movie.
I'm still not certain what the long tunnel was all about with the other type of escape pod or where Chekov's and some of the others Kelvin pods were located.
