I knew an old guy who got a job running a truck on fires back when they still used borate bombers. They told him when you see one coming, get the fuck out of the truck and get the fuck out of the way. That shit is heavy. They said hide behind a tree or rock. One guy crawled under his truck and the borate hit it and mashed the frame to the ground. He came oozing out like hairy play-doh.

I was watching them practice drop with a big Erickson Sky-Crane once. He would dip a bucket out of the river then drop it on the grass airstrip and they would measure coverage or whatever. On his last load, he came over real high and dumped it on the crew. I saw much fist shaking and bird flipping. Ha ha.

That's gotta be about 5 or 6 tons of water...at 8.3 lbs a gallon dropping 15 or so feet. I seem to recall, probably incorrectly, that a gallon of water moving at 15 mph hits at about 100 lbs/ft2

15 feet? That's at least 50' easily. The borate was 2.67 gm/cm3 so it thumped alot harder than water.
