BBC News - The snow patrol drones saving skiers from an icy death

In mid-2015 Robodrone signed a Memorandum of Understanding with the Czech Mountain Rescue Service to develop an integrated solution to detect people buried by avalanches. Our Avalanche Scan Set searches for acoustic signal, the signal is transmitted to the headset and the markers (flags) are released manually via the radio control station. More than 90% of people buried by avalanches survive if dug out within 15 minutes. In short, when it comes to avalanches, time is of the essence.
