Saw this picture earlier this evening and decided to have a closer look at it. Was wondering if the guy situated behind the 757 in the upper left corner (sitting on the bucket) would be feeling the heat of the 757's engine - even if it is only idling? I do remember seeing the damage a 747 engine at power could do to a passing vehicle some 50 or so feet from the aircraft.

From my experience (I work on 757s every day), unless the pilots really bumped up the throttles the most the guy is going to get is about a 60mph warm gust. Sitting like he is it won't probably bother him.
The 747 blowing the truck is a little misleading. The 747 was at TO power and the truck (whose engine was removed) was pulled behind it. The thing took off like a kite.
There is a HUGE difference between idle and TO thrust. So no I don't see a problem here.

Having spent lots of time at that approximate distance behind 757s with their engines running, I can testify that the heat is not a problem. After 25 minutes or so of it, you’ll notice that jet exhaust contains some nasty stuff though. It has about the same effect as spending a day on the beach without sunblock... not overly pleasant. And to think you’ve also been breathing the stuff...
I thought I was doing good trying to avoid those airport hotels... and look at me now.

My favourite spot in winter (while waiting for the loaders to finish, if I don´t have a vehicle), about 10 meters from the APU exhaust of a MD-11 or under the aircon ram air exhaust of a B757 or B767. Unfortunately the ram air exhaust of the 727 is too low to stand under and the one on the A300 blows backwards along the fuselage, not downwards.

Watch where you stand! Twice in the last 6 months CRJ APU's have thrown bits of a gear out of the APU exhaust. Lucky no one was hurt, but one piece went into the side of a parts truck on the ramp!
Arguing with a pilot is like mudwrestling a pig. After awhile you begin to think the pig likes it.

I've used 732 JT8Ds as my morning hairdryers before On a few occasions I did get jetblasted through.
My routine morning "hairdryer" was replaced by dragging a trolley accross the ramp. My usual hair dryer was about to leave, I decided that walking in front of him wouldn't be a good idea and I didn't fancy a lecturing from the Apron Movement Controllers... besides, there was 1 jet holding short of the runway next to the path I would have taken, and another 732 awaiting taxy clearance. So I walked behind my usual hairdryer, this time, dragging a trolley. Just as I was right behind the engine, it spolled up to get it rolling for taxying (self manouvering ramps at this airport)... Well, more surprised than blasted, I fell to the floor... with the whole ramp laughing in my face!
Yes it's warm, not hot During the midday heat, i stand behind props doing engine runs I must be crazy...
