Bryan Snyder filmed this microburst
Incredible! I cannot embed it to play here, but it is well worth watching the microburst... and then in slow motion.
It almost looks like a bomb going off when it hits the ground.
My dad was an airline pilot and got caught in a microburst. He and his copilot got abdominal muscle pulls trying to pull up and out of one. (He swore it was a tornado, but tornadoes don't blow downward, I don't think.)
