Default 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.
