Have you ever seen that training film on jet blast?
As I recall there is a (looks like a 707) would up with brakes locked,
or tied down. A truck drives by maybe 10 to 150 feet behind it. The
whole truck gets, not only blown over, but tumbles across the tarmac
and into the water.

I used to do engine runs on C-130s. Late at night the SPs would get careless
and drive 20 or 30 feet in front of us. It is truly amazing what max reverse on
all four can do to a cop car especially when the poor guy in the car is not
paying attention.
