Airplane impacts

Overview
This page is for collecting evidence relating to airplane impacts, especially controlled tests. Such data can be used to establish what normally happens, so that when there are unknown factors in an uncontrolled, poorly-documented event such as the 4 airplane crashes on 9/11, it can be more easily determined which aspects of the event are normal and which are anomalous.

Video

 * 1984-12-01 Controlled Impact test: NASA, Dryden Flight Research Center; commercial 4-engine jet crashes obliquely into the ground
 * nasa crashes a test plane: probably the same test; not as good a view of the outside, but includes some interior footage
 * Inside a Plane Crash - Nasa Test: definitely the same test, slightly different footage
 * Jet Plane Impact - Test: US government test of an F4 jet hitting a nuclear-grade concrete wall at 500 MPH (multiple angles, low-quality video; subtitles in, I think, Swedish; narration is British female; "crazyshit.com" logo; if this is a US govt test the original video must be public domain, but where is it available?)
 * Lockheed Constellation crash test
