Only flew her for 18 months but seemed to remember it was tried in flight testing possibly with the insistence by the board of trade...Davies?
There were two incidents with Concorde with inadvertent in-flight reverse.. one in cruise which returned; after engineering had crawled over her and cleared the defect it happened again just after rotation...heard her roaring over our cottage near Newbury in the dark; rushed outside as thought it was a car sliding down Cold Ash Hill at high speed on it's roof. IIRC didn't get above 3 grand until over the Bristol Channel.
