Explosion in forest, Naked Gun

So was watching this funny movie and I noticed they used some real footage of a explosion in a forest location, pretty big bomb, any background information of the clip they used in Naked Gun 3 when demonstrating a letter bomb, the clip looks real and only last 3 seconds, it is shown in the beginning just as the bomb goes off, could it be Vietnam footage, either way it looks pretty bad for the local wildlife. Anyway great movie that still holds up

Yes, I think it is a daisy cutter. It one time it was the biggest conventional bomb. A C-130 could carry only one. It was used to clear forests and jungles out for landing zones for the helicopters. They finished it up with chainsaws.

What local wild life? Oh, that goo a mile away covering the trees.

The guy laughing and saying cool, my first thought was the original Beavis
