Did the B1/ B1A have a RAT? I thought that the RAT / AAPP were introduced with the AC system of the B2?
Also, I've never heard of a RAT 'falling off' - and the AAPP would be started by a cartridge in emergency rather than electrically. Although 'Valerie', a 35 Sqn AEO leader cocked things up on the ground and started the AAPP by cartridge, much to the Crew Chief's annoyance as he was surrounded by black smoke and sparks from the cartridge firing. Not to be outdone though, 'Valerie' managed to repeat the performance on a later occasion!
