A net deployment system comprising:
a lengthy housing with a channel therein;
a net folded in the channel;
a lengthy bladder fixed to the housing and in the channel behind the net;
breakaway attachments between the net and the bladder; and
at least one inflator charge for inflating the bladder to deploy the net out of the channel.

### Claim 2 (depends on 1)
