[edit] Speed

The article mentions that the aircraft hit the ground at over 430 mph, and this is described as an extreme velocity. My first thought was to explain why this velocity is extreme, but the article on the ATR 72-212 only gives the aircraft's cruising speed (318 mph). It would be nice to know how fast the aircraft can be pushed in safe flight. -Ashley Pomeroy 17:15, 12 November 2007 (UTC)

[edit] ===============

I think you missed the point. That is an extreme speed for any airliner which makes contact with the ground. Even the biggest ones are not traveling at more than 140 to 150 Kts, when they make normal landings. That speed, and the severe disintegration that resulted, is major evidence that the pilots had lost all control of the aircraft. That was the point: It crashed because the pilots had lost all control.

[edit] Aftermath

Citations were requested for this section. I revised this section to show that although the de-icing boots were extended back further on the chord, by order of the FAA, that amounted to little more than a cosmetic/political band aid, since the icing tests revealed that those planes could ice up all the way back to 23% of the wing chord and to 30% of the tail-plane chord (there have been numerous crashes over the years because of icing on the tail-plane).

I lifted quotations from my own article, at my own website, which is based a lot on the excellent and very detailed research data found in Stephen Fredrick's book. Thus, I posted citations to both my article and to his book. I own that website and the copyright on the article, and hereby grant Wiki the GFDL license to use it. I am not sure if I also need to fill out some kind of form, to make the license legal for Wiki. I will appreciate any help on that point, if this is not sufficient. It is difficult to email my website, due to the spam problem there, so contact me at b o b 9 3 2 at g m a i l dot c o m, if I need to change or add anything, to comply with Wiki rules. Thanks much.
