Really good work there, took a long time to persuede the local council by all accounts. There is a very detailed report on the accident at the NA. As a mid air break up the investigators were very keen to find out how the airframe had failed. On arriving at the crash site they were shown a big pile of wreckage. The local army bods had helpfully collected all the bits from the debris trail and put them in a big heap, apart from the clock which their CO had souvenired and had on his desk. Little was learned.
