I was in a big river with Jack and a couple other kids. There were several families there playing as well. Jack was you, maybe 11.
I was looking into the sky watching helicopters flying around. There were a few.
Suddenly, this big helicopter comes flying in upside down like a meteor and crashes on the riverbank opposite us. Debris went everywhere, and I had the kids stay down until the rotors stopped.
Then I was heading over to help.
