SA100 - VZ999

Stig,
Yes, indeed, there were accident cards. They were kept in the same office as the aircraft record cards and researchers had access to both these useful sources. They were filed by year.
In the days of Aeromilitaria, Jim Halley would pounce on each new batch of annual cards when they became public 30 years after the year in question. This information was published in the next edition of that magazine.
In a perfect world, the aircraft card and the accident card should have been compared—but some seem to have slipped through the net, until now. For the ongoing Vampire histories in Aviation World, we are sometimes using the squadron ORBs to settle ‘disputes’. Andy’s corrections are the result of his de-bugging the next episode for Aviation World.
As a very rough guide, I would believe accident dates in Aeromilitaria’s annual summaries over the individual aircraft histories elsewhere in the same publication (and RAF Registers), but I would not rate them as Gospel.
Remember, information to be written on the record cards passed along several teleprinter lines and though many hands, several of which belonged to National Servicemen who were bored silly with pointless dates and stupid aircraft numbers.
