MUCH of what we read about drones seems controversial or commercial. From the possible crowding of the skies by internet parcel couriers, through the smuggling of drugs into jails, to the use of drones by terrorists, this particular new technology flies frequently on a downdraft of woe.

However, the technology’s potential to be of great value is demonstrated in its deployment by Lochaber Mountain Rescue Team in helping to find lost or injured climbers. Last week, the team’s unmanned aerial vehicle (UAV) located an injured climber on Sgur à Bhuic in Glen Nevis, where there was no phone signal. The UAV was also deployed in the rescue of two climbers on Ben Nevis though, on this occasion, low cloud restricted its use.

Mountain enthusiasts and technology buffs alike have welcomed this use of a drone, which has also been deployed to take photographs for a 3D image of the team’s area of responsibility.

Rescuers envisage making much greater use of drones in future.

Other positive uses for drones are being investigated across the world and include: locating mines; tracking wildlife poachers; patrolling borders; and even laying bricks on high building construction projects. The technology itself is neutral. It is what humanity does with it in different situations that determines whether it can be considered good or ill
