WebIn 2007, the National Transportation Safety Board estimated a total of nearly 24 million flight hours. Of these 24 million hours, 6.84 of every 100,000 flight hours yielded an airplane crash, and 1.19 of every 100,000 yielded a fatal crash. This is down from an all-time high of 9.08 accidents per 100,000 hours in 1994. WebVortex formation flight will allow smaller and stiffer airframe construction, and perhaps most important, the addition of landing gear. ... A- Fighter aircraft are the worst case example for energy harvesting from vortex formation flight because they have small wing aspect ratios (ratio of wingspan to wing chord) and weigh a lot and therefore ...
