First of all a BIG SORRY to those who want this to be a pure MRA 4 thread, but I do believe that it is important that JFZ 90's points are addressed;
(1) The SoS, stated on 4th Dec 2007 that "QinetiQ has conducted an independent investigation into the fuel system and confirmed that, in light of the measures taken since the crash, the fuel system is safe to operate"
(2) In the Exec Summary of the report to which he refers, dated Oct 2007, QinetiQ state, "the recommendations summarised at Section 6 should be considerd and acted upon, where appropriate, before it can be considered that the equipment risks are ALARP. There were some 30 recommendations listed.
(3) In the Exec Summary of the QinetiQ report, dated Feb 2009, it states "no statement can, or has been made as to whether the hot air system risks identified in this report have been reduced to ALARP".
Yes mud does stick, but it stuck because the aircraft had major safety issues. Issues which if they had not been uncovered by "armchair safety experts" would never have been uncovered.
