Sorry to bring the plane up again, this makes me sound like I was talking rubbish.<rant>Hello there pilot, may I ask, what series of the 737 has 4 engines? I can assure you it is not a 737 unless it's the wings and engines of two different aircraft's... OF WHICH you did say, which is fair enough, if that's what you meant.With that assumption how can you tell me it's a Boeing 737 after saying the Wings and/or Engines are sourced elsewhere? (Seeing as there is no other parts of the plane visible.) Which is why I suggested it was a Airbus A340, basing that entirely on the Wing and Engine layout, and the wing tips (of which the 737 doesn't sport).As I said before the knowledge was from a brake-rider/push back driver, whom works with them everyday. (Colleagues also suggested it was a A340)I don't see how you can make such a detailed estimation as you are only guessing like the rest of us.One more thing, I quote "the general electric engines on the wing are far too large for the A340", have you seen the size of the engines on the A340? Same size if not bigger.</rant>Other than that, I agree with what you said.Everyone forgive me for mentioning this again
