You may have noticed more and more gliders appearing in Plane Finder apps and on planefinder.net
These are coming to us courtesy of the great team at glidernet.org
We added some cool glider icons too!
The gliders shown in that screenshot are equipped with FLARM transponders (the name is derived from "Flight Alarm"). FLARM devices are relatively cheap to install and help improve safety for glider pilots by alerting them of potential collisions.
