FB-111這玩意只適合駕駛艙彈射專用,對動輒200~300人的客機是無用的!
除非整個客機機艙完全爆炸分離,再用特大號 XXXXXL的降落傘降落~~~  |
幫飛機加降落傘很瘋狂嗎? 看看什麼是 mission impossible 吧!

飛太高不能彈射 太低一樣不能... 而假設飛機故障 從三萬英呎開始往下降...
第一個要考慮的就是下降的速度 再來才是機身傾斜的角度... 機身搖晃的程度...
達到安全高度後 可以應變的時間.. 我看也沒多久... 射彈椅的反應時間...
掉到安全彈射的高度後 彈射安全高度一般設定於15000呎
最低設定到六千好了... 一萬五千到六千 自由落體下降
大概也只有一分鐘給你反應 假設飛機還有些許動力 再加三十秒......
假設 兩百個彈射椅 算算看一秒要彈多少人... 同時彈射 一次彈2個人(或更多)
那還要計算彈射出去的人不會追撞在一起
而且前面的先彈射機體開了個洞失壓 機身搖晃傾斜程度一定更加劇烈
而且人還不能座太近 不然彈射椅的火箭動力產生的熱 就會先傷害到旁邊的人...
所以彈射的過程就是要快... 但是現在是要彈射數十人甚至上百人...
問題一大堆啊... 要製造出來可能不是空想... 但...

只有一個問題, 人命值多少錢? 換個角度看, 假設飛機在 30 kft (9 km) 出問題, 請問乘客/機長應當如何處置? 要是有第二種選擇, 誰願意與機共存亡!
彈射椅這東西就和汽車的安全氣囊一樣, 並不是裝了之後就能開車衝撞火車. 開飛機撞山. 它們屬於[救命的最後一根稻草]. 有了這根稻草只是多一些活命的機會, 沒了這根稻草那就只能 [兩眼開開準備投胎].
退一步來看, 近十年內的汽車才開始把安全氣囊當成標準配備( 車廠撿過期的免錢專利使用) , 這並不是安全氣囊於十一年前才發明的問題. 裝了安全氣囊的車子於車禍時並不能保證所有的人都能活下來, 但是安全氣囊可能減少碰撞傷害; 雖然安全氣囊有可能在膨脹過程中擊傷乘員臉部, 但是這種傷害與乘員頭臉部直接撞擊方向盤, 儀表版或是手套箱的傷害比較起來還算是可以接受的輕傷. 所以最後大家還是選擇接受安全氣囊的輕傷而不是乾脆讓腦袋撞擊方向盤.
所以當您在努力批判彈射椅的可能傷害時, 您其實忘了不賭這一把的結果就是 [兩眼開開準備投胎]. 這就是贏回 2/3 本錢和莊家通殺的差別!

http://en.wikipedia.org/wiki/Airbag
Patrick W. Hetrick of Newport, Pennsylvania, USA invented the air bag in 1951 and patented his device the following year. Hetrick came up with the idea to help protect his own family using expertise from his naval engineering days. Throughout the years, the saving of many lives have been attributed to Hetrick's invention and highlighted in television shows such as Nova on PBS, or as winners of awards such as the Golden Gear award. There have been devices similar to airbags for airplanes as early as the 1940s, with the first patents filed for those devices in 1958. Early air bag system origins traces back to air filled bladders. These systems were large and bulky, and primarily consisted of compressed or heated air, compressed nitrogen gas (N2), freon, carbon dioxide (CO2), or a mixture of water and potassium (KH2O).[1]
The American inventor Allen K. Breed then developed a key component for automotive use—the ball-in-tube sensor for crash detection. He marketed this innovation first in 1967 to Chrysler.
Air bags become mandatory
On July 11, 1984, the U.S. government required cars being produced after April 1, 1989 to have driver's side air bags or automatic seat belts (the automatic seat belt was a technology, now discarded, that "forced" motorists to wear seatbelts). Airbag introduction was stimulated by the U.S. DOT.[6] However, airbags were not mandatory on trucks until 1995.[citation needed]
In 1998, dual front airbags were mandated by the National Highway Traffic Safety Administration (NHTSA), and de-powered, or second-generation air bags were also mandated. This was due to the injuries caused by first-generation air bags that were designed to be powerful enough to restrain people who were not wearing seatbelts. In the United Kingdom and most other developed countries, however, there is still no legal requirement for new cars to feature airbags, even though almost all new cars now come with at least two airbags as standard.
