Typically it will either: - ride up the nose and then break through the canopy and then run along the canopy sides
- or miss the nose (because the nose is too low to collect the wire) and simply break through the canopy and then continue at through the canopy at the wires height on the fence posts. It is unfortunate that the height of the top strand (or the electric wire) on a typical fence is also the typical height of a pilots neck in a glider. A simple wire cutting device mounted just inside the canopy would be suitable for the first type of entry. The second type of entry (which is probably what happened with the Puchatek) is a lot harder to deal with except for a steel tube cage inside the canopy to deflect the wires. The accident that I was first (bystander) on the scene of, the pilot was lucky and went through the fence at a sideways angle after a failed last second ground loop. He caught the wires across his face instead, but survived to be still flying today. > Please excuse my ignorance, but where does the wire enter > the glider? > > Can it break through the perspex of the canopy? > Or does it slip up the nose and enter into the space > between the canopy and the fuselage? > > If the wire enters the glider through the space between > the canopy and the hull, then it would only take a very > small cutter inside that space to cut the wire.
