I've got a general question concerning 747-100s and in particular a British Airways plane: G-AWNL.
My mom dug out my 'BA Junior Jet Club' logbook form our trip to England in '77 and AWNL was one of the planes we flew on. I looked it up here and noticed in the pictures that it was modified from a 'three window' upper deck to the ten window version. I thought this was pretty interesting and would like to find out more info about this -- and if the modification included any other changes in engines etc. From the order of the pics, the mods must have taken place between 1978 and 1981.
If you know, please clue me in.

No they simply put more windows where there weren't any. The 747's upper deck was originally intended as a first class lounge, dance floor, ... But when airlines started using that floorspace to put additional seats, it became obvious that they would need to have 'standard' windows. Otherwise it would be like flying in a cargo airplane

I am so embarrassed. I really can spell!
The reason that the upper deck needn't be stretched is as Alain said. I might add that stretching the upper deck is also not very difficult. It could be done along with a "D" check without much extra downtime. Splice in a few frame extensions, a stinger or two and rivet on the skin. Voila! You have a -200(SUD). I simplify a bit I admit but it is actually a bit easier than a freighter mod.
Quit calling an airport ramp "Tarmac" and a taxiway "runway".

Many airlines modified their 747-100s (and early -200s) when the upper deck lounges were removed. These modifications happened in most cases around 1980.
Airlines that changed from 3 to 10 include Northwest Orient (all 15 aircraft, that´s 10 -100s, 5 -200s), Condor (D-ABYF), United (747-122s, but not the 747-123s bought from AA!), of course British Airways (all -100s that were delivered with 3 upper deck windows) and others.
