Researchers Make Fruit Flies Perform Aerobatics Like Spitfire Pilots

KentuckyFC (1144503) writes Researchers from Cornell University glued a tiny magnetic bar to the back of fruit flies and allowed them to fly through an electromagnet. Pulsing the magnet then causes the flies to roll in mid-air, like victorious Spitfire pilots. The work isn't entirely frivolous. The team was studying how fruit flies achieve stable flight when they ought to be particularly susceptible to being rolled by tiny gusts of air.

It turns out that fruit flies have incredibly fast reactions. They respond to being rolled within a single wing beat, that's 5 milliseconds, flapping their wings asymmetrically to regain stable flight. That kind of reaction time makes them one of the fastest creatures in the animal world. By comparison, the visual startle response in flies takes 20 milliseconds and the quickest reactions humans can manage is about 100 milliseconds.

    You save only 59 seconds over 8 miles by going 75 instead of 65. Do you really have to pass that guy? Do the Math!
