I have no idea what Lyman has been smoking. His suggestion that the female voice was Bonin's is ludicrous. According to Otelli, the four transmissions in a female voice recorded on the CVR came through on the intercom speaker, were all made by cabin crew, and were all questioning or exclamatory (he transcribes the call at 2:10:59.4 as "Oui?" and the one at 2:11:24.9 as "Stéphanie!").
Even more ridiculous is Lyman's theory that the aircraft was not responding to Bonin's control inputs. It reacted exactly as expected. At 2:11:34.7 (ca. 1.5 min after Bonin had pulled back on the sidestick following A/P disconnect), at around FL360 and TOGA, Bonin announced that he had lost control of the plane and proceeded to pull the stick even further back and to the left and hold it there for 40 seconds.
Equally silly is the suggestion that Dubois, when he re-entered the cockpit, did not want change places with Robert for fear that all control of the aircraft might be lost. They were still at 35,372 ft, surely to God you'd think you'd still have a fighting chance to rescue the situation.
Finally, let's put at rest, once and for all, the impression that all three pilots were experienced veterans of long-haul flying. Bonin definitely was not. Before leaving the FD to take his rest and designate Bonin as PF, Dubois had to assure himself that Bonin possessed an ATPL.
