Not my story, but recycled from another forum I frequent. Believed to be true (I bet someone on here can confirm/refute):
"When my old man was in the army in his early days 17/18 ish he went to lift a lynx helicopter but missed the jack point and put the jack straight through the Kevlar/ally bottom of the helicopter. He spent the next 48 hours straight in work bodging it with fibreglass and paint. A hell of a bodge but no one noticed Monday morning or for years.
25 years later my old man has moved up the ranks traveled the world and now manages engineering for the whole fleet of gazelles and lynx helicopters and other bits. A few aircraft are due a long service overhaul as per normal, a lad knocks on my dad's office door and says your never going to believe this, we've stripped down one of the lynx's and someone has only bodged the bottom with fibreglass."
