I’ve mentioned earlier that if this aircraft is on the ground, it is difficult to hide from satellite observation so would be in a hangar. The Boeing 777-200 is a big aircraft; length 63.7m, wing span 60.9m, height to top of fin 18.5m (6-storey building):
A maintenance hangar is a big thing:
Most Soviet-era maintenance hangars were much smaller and most of the hangars in Central Asia will be of this type. Even if the floor plan is large enough, there is a problem with the height of the fin:
So, often the aircraft are parked as above with the fin outside the hangar, although the hangar pictured above would not take a 777. Now, the Malaysian tail logo is quite bold and easy to identify:
Therefore, if it’s there, it’s only a process of elimination to locate it….if it’s there. Sorry to resort to pictures but I think that some people may find them easier to understand than words.
