On Black Buck 6 the crew chose to decompress at 43 0000 ft on their emergency diversion to Rio so as to get rid of classified planning material, film and crypto through the escape hatch. The noise in the cockpit was horrendous and RT under pressure breathing was a real challenge. The whole event then became an even bigger challenge when the Brazilian authorities refused BB6 permission to enter their airspace. Closing the hatch was problematic and took 25 mins to close with 2 crew members straddled over it in an attempt to force the hatch handle out of its detent with an aircrew knife. Comms under pressure breathing makes you sound a bit like ‘Daffy Duck’ with a tight noose round its neck.
