There is a video of an LC with JATO on Wikipedia:
https://en.wikipedia.org/wiki/File:J...rlift_Wing.ogv (not sure where this was taken; sorta looks like it could be near McMurdo but not it's not any of the McMurdo airfields I've flown into...)
It was slightly unnerving watching the 19-year old ANG guy read the JATO manual prior to its use...
