Three Honeywell employees have flown five successful T-Hawk missions and captured hours of video and dozens of photos of the Fukushima Daiichi nuclear reactor. The four RQ-16A T-Hawk Micro Air Vehicles in service at Fukushima have been adapted to carry radiation sensors. This video continues to focus on Reactor N° 4 :
