Families of those killed in the 1994 Chinook helicopter crash have published 110 questions about the tragedy. They plan to hand a petition to Downing Street. The Chinook Justice Campaign’s petition has more than 47,000 signatures calling for a public inquiry. The crash on the Mull of Kintyre on 2 June 1994 killed 25 intelligence personnel and four Special Forces crew as the helicopter travelled from RAF Aldergro ve in Northern Ireland to Fort George near Inverness. The incident was initially blamed on pilot error, a conclusion overturned in 2011.\n\nThe campaign also intends to deliver a letter to the Ministry of Defence. The 110 questions include who authorised the mission, why that aircraft type was chosen, and whether passengers and crew were warned of the risks. David Hill, the campaign’s technical expert, said sealing key documents until 2094 and the refusal to grant a public inquiry undermine trust in the MoD and the Government.\n\nA BBC documentary last year, Chinook: Zulu Delta 576, showed that files related to the tragedy had been sealed by the MoD for 100 years. Jenni Balmer-Hornby, whose father Anthony Hornby was killed in the crash, said the 110 questions are specific and based on evidence that was withheld or misrepresented. Brothers Andy and Matt Tobias from Watford will hand in the petition; their father John Tobias was killed. The MoD has been approached for comment.
