Save/ShareThis 12-second YouTube clip shows part of a safety video that was created in the early 1990s for airport maintenance crews. In a demonstration, a United Airlines plane on a tarmac flips an airport truck into the water with a blast from its engine.
Now, that's an engine:
UPDATE: 3 p.m. This post originally said that the "United Airlines Boeing 747" was "idling on a tarmac." But, one of the commenters below believes that the plane was misidentified on YouTube and that it was a 757 instead, plus the engine must have been roaring at full blast. Other colleagues have said they doubt the video is real at all. Feel free to weigh in with your own views.

The engine is probably close to full throttle when this video was shot (the audio refers to an engine run). An engine at idle will produce very little thrust.

Hi, Brian,
Thanks for making a thoughtful, authoritative comment.
I’ll add a note. When I wrote "idling", I meant the plane was idle and on the tarmac (not flying in the air—which is what people looking at the post in an RSS reader might assume before they watched).
But I now see how "idling" could be confusing.
Thanks,
Sean

No problem Sean, this was an engine run, something all mechanics do when they work on the engines on a plane. They fire it up and run it to full thrust to make the the plane is working as it should. :-)

Hi Sean,
I work for United and the aircraft in question is actually a Boeing 757 - you can't tell from this short clip, but I have seen the full training video, which was a staged demonstration of the dangers of jet blast. Also, the engine from the "airport truck" was removed prior to the taping. Company officials had no clue it would be blown into SFO bay. Engine idle thrust is quite strong as well; I've seen two co-workers get blown to the ground in an instant.

Hello there. I found your website via Google at the same time as searching for a related subject, your site came up. It looks good. I have bookmarked it in my google bookmarks to visit later.

Of course I like your website, but you have to test the spelling on quite a few of your posts. Several of them are rife with spelling problems and I find it very troublesome to inform you. On the other hand I will surely come back again!
