...fall. Autorotation, which turns a normally soft touchdown into an very hard emergency landing, is at least survivable. It became clear, however, that the design of the Osprey, adjusted many times over, simply could not accommodate the maneuver. The Pentagon slowly conceded the point. "The lack of proven autorotative capability is cause for concern in tilt-rotor aircraft," a 1999 report warned. Two years later, a second study cautioned that the V-22's "probability of a successful autorotational landing ... is very low." Unable to rewrite the laws of physics, the Pentagon determined that the ability to perform the safety...
Helicopter expert Rex Rivolo, who called the decision to deploy the V-22 without proven autorotation capability "unconscionable" in that confidential 2003 Pentagon study, declined to be interviewed. But in his report, Rivolo noted that up to 90% of the helicopters lost in the Vietnam War were in their final approach to landing when they were hit by enemy ground fire. About half of those were able to autorotate safely to the ground, "thereby saving the crews," Rivolo wrote. "Such events in V-22 would all be fatal...

...Most commentators, however, remain resolutely supportive of the couple, including Jones's Daily Mail colleague, Allison Pearson. "I refuse to believe they are guilty unless overwhelming evidence is uncovered," she wrote. Of course, she's basically saying they're innocent until proven guilty - hardly a radical thought, since it's the bedrock of Western jurisprudence. Roycroft-Davis, however, has apparently solved the case. He said on Radio 2: "These people are completely innocent. There's no evidence that I've read that shows that they've got any part whatsoever in Madeleine's disappearance...
