Regarding the jet engine from Phil's picture:
My brother flies 757s and 767s, so I asked him to take a look. According to him, it could be a 757 or possibly a 737 engine. He doesn't usually do the walk-around and there are several different engines certified to be used for 757s. He 's fairly sure that it's not a Rolls Royce engine, but thinks it might be a Pratt & Whitney with a small possibility that it's a GE. He said he could tell better if he could see the cone that Phil is blocking. He's pretty positive the engine is not from the military plane because he thinks those engines are actually bigger than the one in Phil's picture.
Actually the C-17 and the 757 have the same engine installed, the PW2000 manufactured by Pratt & Whitney. Since the C-17 is a military aircarft, they designated the engines as a F117-PW-100. However it is pretty much the same engine.
He thought the picture could have been an engine at a maintenance facility (the engine would be detached from the plane and easier to get to - and easier for a picture to be made); or it could be a prop from a studio lot; or possibly a privately-owned jet (there's a private 757 at the Burbank airport that parks next to where my brother parks when they land that is available to be leased). Or as one poster mentioned, it could be from a museum.
I don't think it is a maintenance facility. It if is, then the engine is still attached to the airplane. Phil is standing on the inlet which means the picture was taken on an actual airplane. If the engine was not attached to the airplane then the inlet area where Phil is standing wouldn't be present. The only place I have ever seen an engine with the entire Nacelle attached is at a Training Facility, e.g. on-site at Pratt & Whitney. However, it is possible that a major maintenance facility could have such a set up.
I believe the picture was taken on an actual aircraft. If the rumor/spoiler about Los Alamitos base being the starting point then I would say that is the most convenient place for a picture like this one. It would have to be some place where an aircraft was parked for a period of time. Getting access to an airplane is not an easy thing. I've had instances where for whatever reason I needed access to a domestic aircraft and I had to plan ahead and go at a time when the aircraft wasn't in rotation (meaning being worked on at the airport facility and is down for the night or day and isn't scheduled for use for several hours). That was usually late at night or early morning.
Also, it is possible that when they were in Seattle that the pic was taken at one of the Boeing facilities. However, that would mean it isn't a 757 since the 757 is no longer in production. However, with planning, contacting the Boeing Media department, time for production to get access to an airplane for pictures could be done. I recall a few years ago, Maroon 5 was onsite at my facility for promotional pictures of them in front on an aircraft or the aircraft engines (I don't recall the specifics).
Therefore, I think is is highly likely the picture was either scheduled or was taken during a long downtime at a facility where production was set up for a long period of time like they were most likely for at Los Al.
At any rate, that's my 2 cents. Now it's out in the open....I work for Boeing and I deal specifically with engines.
