The boys, stuck on a rock, only had one life vest between them. Rather than making a solomonic choice, the firefighters wanted to get another life vest to the kids. The drone, a DJI Phantom 3 operated by Fire Chief Frank Roma, isn’t made to carry large payloads. So they had it fly a line to the youths on the rock, and with the 18-year-old holding on to that line, the firefighters sent over another life jacket. The fire department was then able to rescue them safely.
