I find it hard to believe that the engines tore the wings off. The only information I could find just now was this on the Lockheed P-3 Orion, which mentions the Electra. I'd look longer, but I'm supposed to be working. -rs2 18:26, 10 May 2004 (UTC)

Actually, this is very well-documented. See [1] for a good summary. When the engines were very slightly damaged (e.g. by a hard landing), they could loosen from their mounts and begin violently oscillating, which tore the wing off. Sekicho 08:52, May 13, 2004 (UTC)

Oscillations at fuselage or wing resonant frequencies are Very Bad News. I witnessed a test of a modified Vought F-8 Crusader that was intended to induce such a resonance (for purposes of damping it out). Things went flying off the wings (weights simulating loads). At 26 Hz, all of the power of the hydraulic system went into sustaining the oscillation. Probably 150 horsepower, and very dramatic.

[edit] Electras and P-3's

Just made a small edit to the page, regarding Electras and the P-3 patrol aircraft. Though an early-build example of the Electra was used for testing the P-3 concept, P-3's were different airplanes and were new-built, not conversions from the airliner. The best way to see this is the relative positions of the wing on the fuselage - the P-3 wing is noticably further forward on the fuselage. Hatcat 03:14, 29 January 2006 (UTC)

[edit] Electras in Australia

I just added some text on the use of Electra by TAA and Ansett - replaced by 727 (branded T jets) generally in early 1960's but retained on the "Bird of Paradise" run up to Port Moresby. Used to be my "school bus" each term, to and from Sydney.

Just a note here from Canada... These planes have been modified a little bit and are used as air tankers to fight forest fires. They have the capacity to hold 2400 Gallons of water or retardent. They are operated by a company called Air Spray, based in Alberta, Canada. They are nicknamed "Electra" and are one of the biggest tankers used in fighting forest fires.
