AA Shells Detonation

[alamotex]

John The points you raise are well taken and there is no reason to question the reported bomb damage to buidings that were destroyed during an air raid. I am referring to buildings that sustained damage that left much of the structure still standing. Some published photos show damaged buidings that were not severely damaged, but never a word that it was caused by an AA shell that failed to detonate in the air. The UK town I had in mind had several AA gunsites located quite close to residential housing. It has been reported in one or two articles that the German papers never referred to property damage caused by their flak shells, but military observers knew that this was the case. My question relates to data that must be in the literature, recording the probable percentage of HAA shells that failed to detonate before impacting the ground.( It is too long ago to recall the figure quoted by an IG staff instructor at a AA gunnery course I attended.)
