“Here, we have another sign about airplanes near an airfield or a runaway. This is telling you that gliders might be coming in and out rather than engine planes. Now, gliders are going to be very, very quiet, but they can still give you a bit of a shock if it appears in front of your windscreen, coming in to land at the local airfield or airport.
So, watch out fo them. This one is specifically about gliders.”
