Glider pilots won’t hear tell of carrying any kind of motor aboard their craft which might be used to save them in an emergency (a parachute is just about acceptable among engineless aviators).
I talked yesterday to a gliding enthusiast and she mentioned that when trying to find a landing site, she will routinely seek out any sources of warmth on the ground, as even the sun-warmed wall of a hut can provide a lifesaving updraught.
Today’s invention is a magazine of high intensity flares which are dropped on the ground when a glider pilot runs out of lift sources and landing sites.
The pilot flies in a circle and and drops the flares at intervals. These have a brightly coloured casing and when returned to the owner, provide the retriever with a payment. They have an insulated base so that heat can escape only upwards.
On a second circuit, this time over the flares, the glider picks up enough altitude to hedgehop home.
