Mid-air Collisions
A comment elsewhere about the Pinner, or Northwood (depends which report you read) collision in 1948 between an RAF York and a SAS DC-6 led me to a search on Wikipedia, and I was astonished by the number of mid-airs between military aircraft, especially through to the 70s and 80s. Indeed the Northwood accident is claimed to be the last mid-air involving a civilian airliner in the UK. Anybody else looked at this aspect of aviation history. I found a long article about the Norhwood accident in a paper written for the local history society. I was surprised that I have no recollection of the accident itself, nor my parents discussing it, and we lived only about 4 or 5 miles from the crash site.
