B-747 From 3 UD Windows To More?

Sat Jan 21, 2006 4:18 am

I was checking some IB pics and came across one of IB's 747's EC-BRQ.
In the first one you can clearly see that it has three windows in the upper deck.
In the next one it has the more conventional layout with more windows.

Is it possible that the aircraft was later reconfigured to that standard? or maybe there is a mistake with the registrations?

Thanks for the information.

Boeing offered a MOD as the -200s came online resulting in an extended interior upper deck.

Airlines could choose to plug/unplug as seen fit. Ther'es a better explanation out there, but the windows in the UD went from 3 to 8 to 10 finally on the -200s and late -100s

One of the reasons, I would guess, is as they put regular seating up there (replacing the "inflight lounges" that the early '47s had) people wanted a window for each for row of seats ...

At least that's how I'd imagine it going ...

BA converted all 747-100s (most of which were delivered with the 3 window upperdeck and apparently the lounge up there) with the 10 window solution around 1980. Northwest did that too in the late 70s, as did other airlines.

TWA's later 747's all had the 8 or ten windows, but they were all plugged for fleet commonality. This sadly became the basis for speculation when flight #800 crashed - the coverings popped out revealing the larger number of windows, and some thought it was evidence that the investigation was a fraud.
