Post by ZZyXXwhere there ever any tests prior to Trinity of large non-nuclear explosives
Well it was not a test but there was a very large explosion at an RAF
bomb dump in 1944 that produced an enormous crater.
"The RAF Fauld explosion was a military accident which occurred at 11:11
am on Monday, 27 November 1944 at the RAF Fauld underground munitions
storage depot. The RAF Fauld explosion was one of the largest
non-nuclear explosions in history and the largest to occur on UK soil.
Between 3,500 and 4,000 tonnes of ordnance exploded—mostly comprising
high explosive (HE)-filled bombs, but including a variety of other types
of weapons and including 500 million rounds of rifle ammunition. The
explosion crater with a depth of 300 feet (91 m) and 250 yards across is
still visible just south of Fauld, to the east of Hanbury in
Staffordshire, England. It is now known as the Hanbury Crater.
A nearby reservoir containing 450,000 cubic metres of water was
obliterated in the incident, along with several buildings including a
complete farm. Flooding caused by destruction of the reservoir added to
the damage directly caused by the explosion."
