If you wanted to be a firefighter as a kid and never got to, here's the next best thing:  A filmmaker in Detroit made a three-minute short of a burning house using helmet cams on the firemen.
First, one of them walks onto the front porch while the whole house is on fire.  Then it shows the point of view from a water cannon.  And it also shows a few shots from inside.
It's from a full-length documentary called "Burn" that's set to premiere at festivals this spring.
