Soldiers of the IDF Skylark I-LE unit spent a week earlier this year in the Negev Desert, learning how to operate the Skylark drone. The drone is lightweight and unnoticeable up above. It boasts 3 hours of flight-time while streaming a live video feed day and night. It has a range of 6 miles.
Recovery involves landing the drone on a small inflatable cushion.
