Review for Altitude by Dean Crawford. 
"Then there is the narration - or should that be production? This is so well done, it feels like a whole cast of actors has been employed here, rather than just Greg Patmore. His ability to become each and every player individually is remarkable and, by slight technical effects for such details as conversation via communication systems, made very real. His reading voice for the ongoing text is American but the British pilots' accented voicings and other nationalities of the passengers and flight assistants is absolutely spot on. Is this really just the one narrator?" *****
