While standing in line at the grocery store a few weeks ago, I was looking through "The World Weekly News" It has fake stories and unrealistic things that supposidly happened around the world. One was about a guy that was drunk or something and opened the airplane door and jumped out. Unbelievable I know. Anyways to the question. The article showed a L-1011 landing but it had 4 engines, the rear engine and the two wing engines. However, under one wing there was a "fourth" engine. So if you can picture it in your head, it had 2 engines under one wing (close together), one engine on the other wing and the rear engine. Is this a fictional plane, or is it real? If it is real, does airliners.net have a picture of it? Thanx for your help

Chances are that it --is-- real. The airlines do this (strap an extra engine on..it's less common now) to deliver the extra engine to a plane that needs a new one, whether it be domestically or internationally.

I have seen this. A few years ago BWIA International needed to ferry a RB511 to RR in England so they attached the engine (just as in the picture of the 747 in the previous message) on one of their scheduled flights to LHR
Sorry I didn't use this one earlier, but I didn't even think to look for it...duh! OK, now I know this happens with 747s and L-1011s--do any other aircraft do this?
Regarding FRA_to_usas questions, of course it doesn't threaten the structural integrity--it's designed to do this! It does, however, add drag so there would be a performance penalty (then again, any cargo would affect performance). Also, why would an airline want to pay someone else to ship it? That would take time and great expense--it would be much quicker and cost-effective to transport it along with the rest of the cargo on their own revenue flight. I've seen aircraft sit for days at a remote location after some mishap waiting for a new engine to arrive by truck--what a waste! Also, I know on the 747, they mount devices on the spare engine to reduce drag, since it is inoperative.

The 747 and L1011 were designed to have this capability (The DC-10 was not).There is a mount in the wing for this very purpose. On at least two occasions I saw a CO 747 transport an engine in this manner.

The fourth engine is a spare"pod" it is used to move engines from one place to another. That engine does not produce thrust, no fuel or other hook ups other than the two mounts. DC10's and 747's also have the same pod .
