It turns out that small drones can leave a big impact on large aircraft. Scientists at the University of Dayton Research Institute discovered this when they flung a DJI Phantom 4 drone into the sky from a cannon. It didn't take very long before the drone crashed spectacularly with a Mooney M20 airplane. Luckily, the collision was staged as part of a study and no one was injured in the process. For the study, researchers worked to mimic a midair collision between a 2.1-lb drone and an airplane at a speed of 238 miles per hour.
