I’m trying to track down any good articles/books covering the RAF supply effort to Warsaw during the 1944 uprising.

Stan,
try:
Airlift to Warsaw: The Rising of 1944 by Neil Orpen,
The men who went to Warsaw by Lawrence Isemonger – about 31 and 34 Sqn SAAF,
for a wider image – Rising ’44 by Norman Davies,
and finally an excellent website about Warsaw Uprising – http://www.warsawuprising.com/ – there is few stories by the airmen themselves in “witnesses” chapter.
