F35基于错误的理论"飞机的机动性无关紧要,让导弹做转圈的活. "
* 第一, 假定F35能撑到可发射导弹的位置, 但是J20和T50拥有低可探测性, 又非得多
快得多, 因而使他们的下视下射导弹拥有先发制人的优势;
* 第二, 更危险的是, J20和T50有超强的应对来袭导弹的措施(包括超机动, 隐形等,超
高速,及电子对抗措施, 让F35会转圈的导弹无法得手.由于自大地认为敌人的导弹无法
穿透F35隐形技术的屏障,F35的相应应对能力要差得多.
* 第三, F35紧急应变能力原本似乎不必要的,但现在J20依仗其隐形和高速会飞快地出
现在打完导弹的F35面前,迫使它进入并不擅长的缠斗.

Although several recent Western fighter aircraft are less detectable on
radar than previous designs using techniques such as radar-absorbent
material-coated S-shaped intake ducts that shield the compressor fan from
reflecting radar waves, the F-22 design placed a much higher degree of
importance on low observance throughout the entire spectrum of sensors
including radar signature, visual, infrared, acoustic, and radio frequency.

warfighters in Iraq that allowing gays to serve openly in the military will
have little impact on the armed forces, an argument largely echoed by the
top leaders of the Army, Air Force, Marines and Navy.
Visiting troops at Camp Liberty in Baghdad, Gates was asked when repeal of
the 17-year-old policy commonly known as "don't ask, don't tell" would occur
and what its effect would be.

A plausible explaination given somewhere else: the pitot tube was plugged by
ice, and by the interaction of ice expanding and pitot tube's working
method somehow was giving indication that air speed was increasing, instead
of dropping. So the pilot mistakenly concluded the aircraft was in a dive,
so they pulled nose up and reduced thrust to come out of it. |

1. 事故回放
Air France 447航班，机型：空客A330-203，注册号：F-GZCP，于2009年5月31日(巴西
当地时间)执行从巴西里约热内卢至法国巴黎的航班任务时，在南大西洋上空，距离巴
