The following sequence of images demonstrates what can happen to an aircraft if too severe a pull-up is attempted. The images were captured from a Farnborough Above and Beyond: The True Story of British Aviation free sampler disc that came with the January 2007 Issue of Aeroplane. The sequence was from a The Investigators part of the Main Movie.
Now I do not know the precise circumstances of the aircraft which could have been returning with battle damage but it is much more likely to have been filmed whilst under test. The aircraft appears to be a Lockheed Hudson. The Armstrong Whitworth Albermarle was very similar in form but the shape and positioning of the fins make it more likely to be a Hudson. The first image shows the aircraft in a shallow dive appearing just to the right of the large tree at the left. I have included trees and horizon in some shots so as to provide some idea of the height and distances moved. Next image shows the aircraft leveling out. In the next image trouble can be seen but less than obvious, compare the angle of attack of the starboard wing with that of the port. Now the next image shows clearly the result of torsional stresses appearing in the starboard outer wing. By the time we get to the next image failure is becoming obvious and proceeds apace.

In the next image the starboard outer mainplane having completed its detachment has caused the aircraft to move even further out of its flight envelope with the tail plane now clearly failing, the aircraft is of course doomed.

I didn't find this specific "wing failure," but Lockheed Hudson crashes (most looked to be engine failures) are listed at:
http://www.planecrashinfo.com/famous1940s.htm http://www.skystef.be/Belgian-regi-p5.htm http://www.rafdavidstowmoor.org/pages/cras...crashlog43.htm# It wasn't crash-specific, but the RAAF Hudsons were mentioned in the Battle of Ambon: http://en.wikipedia.org/wiki/Battle_of_Ambon EDIT: About the Lockheed Hudson aircraft itself: http://www.uboat.net/allies/aircraft/hudson.htm http://home.att.net/~jbaugher4/a28_2.html http://www.xs4all.nl/~fbonne/warbirds/ww2h...lockhudson.html http://en.wikipedia.org/wiki/Lockheed_Hudson |

QUOTE (dMole @ Nov 6 2008, 05:08 PM)  I didn't find this specific "wing failure," but Lockheed Hudson crashes are listed at: There was another similar Lockheed aircraft - the Ventura. However I have searched my copy of 'UK Flight Testing Accidents 1940-1971' without luck. I also checked out all the CAT 5s (write offs) on other twin finned, twin radial types especially those from Bristol even though their profiles were subtly, but distinctly, different such as the Brigand, Buckingham, Buckmaster and some marks of Beaufighter. I used to see examples of those Bristol types in the air in the early 1950s – some family worked at Bristol's and my old man was a design draftsman for Rotol (prop's and gearboxes). I have seen the Brabazon in flight too. |

I didn't see our mystery plane there, but Wiki has some lists of accidents/incidents O892 (with 2 wing failures listed for other aircraft types):
http://en.wikipedia.org/wiki/List_of_accid...craft,_pre-1950 Lockheed Ventura and wing failure came up in a Skunkworks .PDF eBook, but I haven't researched it fully. The search engine says "Lockheed Ventura II AE852 YH-S of 21 Squadron based at RAF Ou... " but the page doesn't at: http://www.rafdavidstowmoor.org/pages/cras.../crashlog43.htm There are several Lockheed Hudsons and Venturas showing at the following Irish page: http://www.csn.ul.ie/~dan/war/crashes.htm Down in Oz: http://home.st.net.au/~dunn/crashnsw.htm |
