Anyone know more about TBB and
TBD? Am I about right?
TBA BOAC 4 x Hangar bays and sim hall still active.
TBB BOAC Britannia / VC10 wing hangar, demolished? Is that what the story below refers to?

TBC BOAC offices still is use.
TBD BEA hangars by Cathedral? One bay demolished early 2000s?
TBE BEA Cathedral hangar still in use.
TBJ/TBK BOAC B747 hangars
TBN ex bmi hangar (also described as
TBD?)
google was not my friend on this.
That's substantially correct.
TBB was on the south side of what is now Envoy Road (currently a huge car park).
The original
TBD (aka "East Hangar" or Bays 11-20, including workshope, engine test cell, etc in BEA days) was on the site of the current blast pen (you can still see the footprint of the building on GE). The designator
TBD was later recycled for. I think, the BMI hangar.
TBE (aka "West Hangar" or Bays 1-10) is indeed the one to which the Cathedral hangar was bolted on (losing access to Bay 1 in the process). Bays 6-10 have been demolished together with the offices above. I have a feeling that what's left - the bit visible from the CTA - may be listed, which is perhaps why it still survives.
Other notable buildings to have vanished over the years include Speedbird House, Comet House, Viscount House (and extension) and, most importantly, the Runway and Hatton Cross canteens (I assume the one inside TBA survives).
