The movie showing the F15 with only one wing, looks over exposed, ( especially on the side with a missing wing ), while all other cuttings are normal !

You can do weight shifting with your paraglider, but I can't see how the F15 pilot can do the same with a plane :roll:

It's impossible to capture the inccidence from all those different camera angles.

I don't think it is real.

條片入面隻 F15肯定唔係出事果隻黎架啦﹐我估係做出黎令觀眾有個 visualization 嗟。但臨尾果張硬照睇落就係真。旁白話飛機公司都覺得隻 F15 無左一邊翼都飛得係好離奇﹐所以派人到以色列研究。無左一邊翼都飛得似乎唔係 by design 而係純“符碌”﹐Macdonald Douglas 既專家研究後所得既結論係因為 F15 個機身非常扁平﹐能夠好似一隻翼咁產生升力。加埋剩番果邊翼﹐要托起隻機真係唔難。因為好似 Pitts 呢類螺旋槳機做 knife edge 果陣都可以單靠機身則面產生足夠升力﹐F15應該更加得。但我諗唔明就係點解隻 F15 係升力偏埋一邊果陣隻機唔會 roll. 諗左一排推測隻機應該係俾著 rudder 黎飛﹐好似咁 ﹕

另一個可能就係隻機無左一邊翼﹐重心走埋一邊﹐剛剛好疊正條升力線既新位置﹐所以可以平飛。咦 ﹖咁咪同滑翔傘用單邊傘翼飛行既原理一樣 ﹖

阿麥﹐不如搵你隻 New Sting 試下啦﹐唔要一邊 wing tip 都好有可能飛到架渦﹗我唔係講笑架﹗有人試過 Shooting Star 唔要 V 尾飛。真係不妨試下我個建議渦﹗
