The video is real. It was staged to demonstrate the effects of jet blast for a safety video. The engine was removed from the vehicle to make it lighter and it was towed behind the 747 by the fire truck visible in the lower left corner of the frame. The 747s engine was at T/O power. The combination of an engineless vehicle and T/O power does exagerate the typical result of driving behind a running jet but most viewers of the tape weren't informed of this detail.
This particular video cost UAL a LOT of money. It seems the EPA got involved when they found out that UA hadn't properly decontaminated the vehicle from its various fluids, etc. Our trainers at UA told us a big lawsuit ensued following the filming of this demonstration.
The day before we got to SXM, I was told a man got blown from the fence to the water off the beach and broke his arm landing in the water. I saw alot of sand and people getting blown around, but no serious injuries. It was quite a sight.
A liberal is a man who is right most of the time, but he's right too soon.
You see pictures of people standing on the beach as 747's fly over head.
Aren't they blown away by the jet blast?
Well, the power setting of an a/c taking off is totally different to an a/c on short final. Most a/c on short final is usually on idle power setting, therefore the jet-blast is very minimum. The noise may still be very loud, but it's not as powerful as an a/c at take off power.
They did a demonstration over here in the uk like that, virgin 747 and engine at take off power, then drove t cars into the jet blast to see which was better (its a program called top gear, for car nuts).
Theres a pic of them filming, and a bit of a description too.

first of all, what a**holes for suspending the site because it is popular.
That video is a bit deceiving. The audio track is of a single or of a set of engines at idle. The engines on the United aircraft are obviously at full throttle. Idle engines would not have that affect on a passing vehicle. But Engines at full thrust are producing winds of 200-250 miles per hour.
It isn't often you will be able to drive directly behind the threshold of a runway while an aircraft is initiating its takeoff.
If a pilot needs to do a runup, s/he is directed to an area with a blast fence. Gate runups are not allowed for this exact reason (see video).
If this is a 777, that is realistic if it is set at idle. For de-ice training at DL, it tells us that they need to shut down their engines due to the 100mph+ winds that it produces at idle. So if they have it advanced to maybe 10% or less, what you see is a realistic probability.
This is not a 777. I could not find a single picture in airliners.net of a 777 in that livery. It didn't exist.
Second, even if this was a triple 7, the jet blast would not be strong enough to lift a car off the ground and toss it into lake. For de-icing, you are not required to shut down because of the possibility of throwing your truck into the next awaiting aircraft. Yes there is jet blast at idle, but the engines are shut down due to intake hazards and slight discomfort from the rear of the engines the person in the bucket may feel.
A friend of my father's was following a VW Bug on a mountain road in Colorado in the 60's. When he went around one curve the Bus was no longer there - wind had blown it off the mountain. When you think that the two engines on a fully loaded 767 throw out enough air to get the plane up to take off speed and then into the air it's rather clear that a car wouldn't have a chance - with or without the engine.
**""The bridge that connects the Michigan Pennisula to the Main part of Michigan, haven't cars been blown off it into the lake during high winds?""**
Yeah in the late 1980s some lady driving a Yugo got blown off the Mackinac Bridge. She was actually a friend of someone I knew. I feel guilty because before I knew that we used to make jokes about Yugos blowing off of bridges.
I think the winds were 40 mph that day on the Mackinac Bridge
The video here is not the original one produced. It was made for airport personnel to show the affects of driving around a large aircraft with its engines running. This is a 747-100 or 200 aircraft. I'm trying to find a copy ofthe whole video which shows the aircraft, it's about 2-3 minutes long.
