I have a hazy recollection of a Javelin on QRA at Leuchars in 1961/62. Young LAC sent out by Chief to renew BF status, playing "hangar-pilots" and managed to arm and fire the Red Top/Firestreak out over the Eden estuary! All hell broke loose, but I can't remember what happened to the poor unfortunate! I was on 228, SAR choppers, and had to go looking for the practice missile remains.
Kind regards,
