It's a risky venture, opening a story in the thick of an action sequence. It also seems a tad short for a chapter, but that's not really a problem, especially if its meant to be a short story.

The action itself is engaging, and fast paced. Sometimes, the writing gets a little loose, but it doesn't hurt the story all that much.

There's probably a lot more I can say about this, but my brain seems to have shut off. Perhaps another time. Do keep writing...
