The tests are, mostly, carried out on a platform called a shake-table which is designed to shake in the same manner as an earthquake. Results of those tests often include the corresponding shake-table videos. Testing of structures in earthquakes is increasingly done by modelling the structure using specialist finite element software. Destructive software testing is a type of software testing which attempts to cause a piece of software to fail in an uncontrolled manner, in order to test its robustness and to help establish range limits, within which the SW will operate in a stable and reliable manner. Automobiles are subject to crash testing by both automobile manufactures and a variety of agencies. There has also been extensive destructive testing of passenger and military aircraft, conducted by aircraft manufacturers and organizations like NASA. The 2012 Boeing 727 crash experiment was conducted and filmed by the Discovery channel. RAF Strike Command  The Royal Air Force's Strike Command was the military formation which controlled the majority of the United Kingdom's bomber and fighter aircraft from 1968 until 2007 when it merged with Personnel and Training Command to form the single Air Command. It latterly consisted of two formations – No. 1 Group RAF and No. 2 Group RAF. The last Commander-in-Chief was Air Chief Marshal Sir Joe French. Strike Command was formed on 30 April 1968 by the merger of Bomber Command and Fighter Command, which became No. 1 Group and No. 11 Group respectively. Signals Command was absorbed on 1 January 1969, Coastal Command was absorbed on 28 November 1969 and Air Support Command (formerly Transport Command) was absorbed on 1 September 1972. In 1975, the Command doubled as NATO, Commander-in-Chief United Kingdom Air Forces (UKAIR). UKAIR fell under NATO's Allied Command Europe in Mons in Belgium. In case of war with the Warsaw Pact the command would have commanded all Royal Air Force units in the United Kingdom as well as the US Air Force's Third Air Force based at RAF Mildenhall with its subordinate wings and squadrons. Reinforcements coming from the continental United States, as well as units transitioning to other European fronts, would have also come under UKAIR. RAF Germany was absorbed as No. 2 (Bomber) Group on 1 April 1993. The RAF's Process and Organisation Review concluded that Strike Command and Personnel and Training Command should be co-located at a single command headquarters: it was subsequently decided that both commands should be located at High Wycombe and in 2007 Strike Command and Personnel and Training Command were merged into a single command – Air Command. Headquarters Strike Command (often abbreviated to HQSTC) was located at RAF High Wycombe in Buckinghamshire.
