A total of forty one Grand Slam Bombs were dropped in WWII mainly
against bridges & viaducts during 1945. Only about 5 foot longer than
it's 'little' brother "Tall Boy" yet twice the weight.
The "Tall Boy", designed by Dr. Barnes Wallis, reached the speed of
sound during descent from about 20,000 feet and on impact made a 80
feet deep by 100 feet wide crater & could penetrate 16 feet of
concrete after going through up to 90 feet of earth ! First used in
an attack against the Saumur Rail Tunnel in the Loire Valley
Concerning the explosive effect of the 'Gate Guard' Grand Slam ......
if BOTH it's special steel alloy casing and the Torpex explosive was
still in reasonable condition then the authorities would have been
correct in being so cautious but I think the story itself is a bit of
what you might call 'Urban myth'
I think they still have empty (?) Tall Boy & Grand Slam bombs at the
Brooklands Museum near Weybridge
I wonder if there are any working examples? If so a good place to
demonstrate one would be Walford, thereby relieving the suffering
of millions ;-)
