But because these aircraft are light, they are also vulnerable to gusts of wind that can fling them off course and disrupt any observations they may be making.
Now, Peter Ifju, an aerospace engineer at the University of Florida, US, and colleagues have developed an aerofoil, or wing shape, that flexes in the wind in response to gusts of wind.

In such a gust, the leading edge of each wing warps to reduce its angle of attack and keep itself pointing into the wind. This flexing can be controlled in such a way that the wing maintains level flight during gusts of wind, Ifju says, and the result should be a smoother ride in blustery conditions.

So the US Air Force funded a US company called Luna Innovations to develop an easier way to spot damage.

The technique that Luna Innovations has come up with is to coat an aircraft part with a polymer containing a fluorescent dye held in tiny capsules. If that part is struck with force or twisted beyond a certain limit, the capsules break releasing the dye. A visual inspection of the aircraft then reveals exactly where any damage might have occurred.
