The drone that crashed into a Florida panhandle highway last year was caused by a bad controller, Air Force investigators report. There was a problem with the autopilot systems controlling the up and down movement of the aircraft. This in effect caused the plane to malfunction and crash. The highway effected, Highway 98, was closed for over a day due to the crash and the subsequent fires that it caused.
The Air Force estimated over four and a half million in damages, including those to the drone, the highway and the runway where the drone took off.
Once airborne, the drone was only in flight a few seconds before the malfunction brought it down.
