Project Albert was a fast moving, complicated project. Lots of interesting information here.

3 “bomb assembly kits” were shipped to Tinian per the above source. Another source indicated the 3rd unit was held in reserve in CA and/or test assembled in CA. These (kits) were complete independent bases, buildings for administration, assembly and operations, all the equipment, scientific gear, etc EVERYTHING.

Two were assembled. On sept 7 disassembly began and they were dropped in the ocean for security reasons.

'Project Alberta', GREAT stuff, thanks for that!

Reading over the material, I saw "The bomb run began at 09:12, with the drop three minutes later. Simultaneously the B-29 'The Great Artiste' (Instrumentation plane) dropped its three Bangometer canisters"

No question they recorded one helluva 'BANG'. ;)
