http://www.britishpathe.com/video/air-crash-at-bristol-airport/query/Aer+Lingus+plane+crashWeather deteriorated as the aircraft approached Bristol. The Viscount was misaligned with the runway, which the pilot tried to correct at flare-out level. The right wingtip and no. 4 propeller struck the runway during this manoeuver. An overshoot was attempted, but the pilot saw obstructions coming up ahead, which he wouldn't be able to clear. The pilot thus put the aircraft onto the ground wheels up. The Viscount came to rest against a fence.
PROBABLE CAUSE: "An attempt to align the aircraft with the runway at too low a height following the commander's incorrect decision to continue the approach when visual guidance became obscured below critical height."
