i used to do aerial surveying stuff for this construction company...took pictures of dirt piles with $20, 000 cameras...anyways...we used a tomahawk with a special homemade photo window...he'd basically lean out the thing and i'd put it into a monster slip...which is probably the easiest way to crash a tomahawk...anyways they liked it and we did a lot of work with them...

it takes a certain kinda guy to slip it just right...
