Looking at the R101 crash, the author of OTL was really not being subtle in their attempts to kill of British airships.
An airship crash that takes out the Minister who's been most avid in promoting them, the Director of Civil Aviation, the Director of Airship Development, the Assisstant Director of Airship Development and the Officer in Charge of Design and Research at Cardington in one fell swoop.
I mean it's almost as if we're being written by someone from a world where British-developed airships ended up being the dominant form of transport and the author went over the top in terms of making sure everyone who was involved in setting it up was killed off.
Have the winds be acceptable when the 100 MPs are on board and have a crash then...
Serious PoD capability. I don't know who the 100 MPs were, but in November 1929, we had such people in the House as:
Megan Lloyd George, David Lloyd George, Gwilym Lloyd George, Robert Boothby, Isaac Foot, William Wedgewood Benn, Stanley Baldwin, Leo Amery, Neville Chamberlain, Austen Chamberlain, Hugh Dalton, George Lansbury, Archibald Sinclair, Samuel Hoare, Phillip Snowden, Eleanor Rathbone, Herbert Samuel, Nye Bevan, Winston Churchill, Manny Shinwell, Clem Davies, John Clynes, Ramsay MacDonald (All right, it's unlikely the PM would have been there without it being mentioned), Oswald Mosley, Clem Attlee, Anthony Eden...
It beggars belief that one in six MPs could be on board without at least some of the above being there.
