I was a loadmaster in the 50 TAS CCK 71-72. Did numerous bomb drops in V/N and cambodia. I have slides somewhere that I took of the extraction and blast.
I followed it all the way to the ground, taking pictures laying on the back ramp. Just like a small nuke going off, big mushroom cloud!! We where at 5000 feet and you still got a bump from the blast.
Long time ago.
