Thank you Sabrejet. This was the same webpage that I managed to find some of the accident report reel numbers from, but it does not include those for 1945 onwards, nor does it list the minor accident report reels.
On the subject of AFHRA requests, when I first started requesting reels you were allowed 10 reels per month, this was later dropped to 5 reels per month. The current policy is you can request 10 reels at a time, then request 10 more once you have received those. Like you say, the wait can be lengthy. My last request was on 13th January. To date I have only received 4 reels, and one of these was the wrong one. Sent two further e-mails regarding my request and have not received a reply to either e-mail, and this was 3 weeks ago. I think the current policy of 10 reels might have drowned them in requests which they can't cope with.
