Rallye Driver
The AIIB didn't find the direct cause of the apparent brake failure in the L39 crash - the investigators were unable to reproduce the problem - but the comments about certain aspects were as critical (restrained AAIB style) as I've ever seen in an AAIB Report.
I agree it's entirely wrong for the media to use either incident to suggest Duxford isn't safe. There's no basis for such criticism in the L39 Report.
