The Dornier Do 24 was a pre-World War II flying boat designed for anti-submarine and search and rescue duties. It saw service throughout the war, mostly in the German armed forces, but also serving the Dutch in the Far East during their brief war against Japanese invaders. Thereafter the survivors served in Australia until the end of the war. Its design was not dissimilar to the famous Consolidated PBY Catalina of the same vintage.
Late last century one of the few surviving Do 24's was re-engined with turboprops, and used by Dornier to test the Advanced Technology Wing that was designed for the Do 228 transport. Since then it's been flown by a foundation in support of UNICEF and other charitable causes, piloted by Iren Dornier, grandson of the founder of Dornier Aviation.
Last month, at the 2015 Scalaria Air Challenge in Austria, the plane suffered a mishap. It was landing in perfect weather when the pilots noticed an obstacle on the surface of the water. They tried to make an emergency turn to avoid it, but the aircraft was moving too fast to respond properly, and spun completely around. The skin suffered damage, and some of the frames and spars will have to be inspected in detail to make sure she's still airworthy without more extensive repairs.
Here's a video clip of the incident. The title's completely wrong: whoever put it up seems to have thought this was a stunt, when in fact it was an extremely dangerous situation that could have resulted in deaths, injuries or the loss of the plane. Also, they had to add a music soundtrack . . . when will people learn that music is often more of a distraction than an aid to watching? At any rate, it shows the incident very clearly. Watch in full-screen mode to see all the details.
I think the crew of the Do 24 were very lucky indeed. I'm glad so historic an aircraft survived, and will be flying again soon, all being well.
