A recently discovered internal Ministry of Defence memo has shown that there were very serious concerns about the safety of the Chinook Mark II helicopter fleet, several months before the fatal crash on the Mull of Kintyre in 1994. The special forces crew and 25 senior members of Northern Ireland's intelligence community were killed.
A Royal Air Force investigation finally found the two pilots guilty of gross negligence. As well as the official reports, including Select Committee on Chinook ZD576, you can also find the House of Lords' discussions about it online.
Along with Sir Stephen Young's conclusions after the Fatal Accident Inquiry, we also have CD-ROMs containing the transcripts. These were supplied by Steuart Campbell, who wrote a book about the incident.
