Martin- Good story on grand slam- The upsurge felt on release of such a bomb would indeed be tremendous. We were well aware of the impact felt with the release of our bombload. They ranged from 250, 500, 1000, 2000 and up to the 4000 "cookie").
I"m not sure how they achieved the required lift. Our all-up take off wt. was 65,000 lbs. Now a Lancaster's tare wt. was 43,000 lbs. Add ammo, fuel and crew
and we're well over. However those boffins could do wondrous deeds those days
