HP-18J Twin Turbine Self-Launch Sailplane
Noise is usually a big problem with this type of power plant.
If the noise is exceptionally loud, we could not allow a takeoff at our gliderport.
The towplanes (Pawnee) produce a lot of noise, however, it is in a different sound level, and more acceptable. Further, the locals are used to it after 40 plus years
A turbine launch would draw more attention to towing activities and perhaps draw more attention to noise made our conventional towplanes.
