The first picture was taken by me years ago at Brooklands and shows a Grand Slam bomb on the left out side what was the motoring club house and the one on the right a part size Tall Boy experimental bomb. The site was taken over by Vickers in WW2 and these bombs were displayed outside for many years before being put under cover in the late 1980s. I believe that Barns Wallis office was on the 1st floor and his office window is between the 2 bombs. This is where he did much of his design work. This is now part of the Brooklands museum and is well worth a visit.
The 2nd and 3rd pictures shows the result of a Germanmine laying aircraft being shot down over Clacton on Sea, Essex on the 30th April 1940. Amazingly only 2 on the ground were killed but 160 were injured.
