Popular Mechanics- Last fall Rutgers University ocean researcher Oscar Schofield headed a collaborative experiment called Gliderpalooza, which coordinated 15 aquatic, submersible research drones to sample the deep waters off the coastal Atlantic. About 5 feet long and shaped like tomahawk missiles, the gliders beam home their data every time they surface. The propellerless drones, jam-packed with scientific instruments, swim by changing their buoyancy—taking on and expelling a soda can's worth of water to sink and float.
A $230 pocket-sized drone that can only fly for three minutes.
In the span of 13 months, eight drones have crashed.
Attacks like this one are likely to become more of a problem in the future.
