Errmmm if you read again it makes perfect sense... your explanation of the vanes backs it up too...
In both cases, bomber or jabo, the vanes are required to do their thing. No matter the velocity the vanes will arm the bomb after it has travelled X amount of distance. Sure the faster bomb will reach that distance quicker than the slower bomb....
Right now the bomb has to travel 1000ft, in any direction...
Those vane things... would they arm the bomb in time if a divebomber dropped the bomb from 500ft? Divebombers typically released ord MUCH higher than that...
Retarded bombs weren't they intended for low LEVEL drops, not 70deg dives?
