(Note: USS SALADIN designed by Franz Joseph, from the Starfleet Technical Manual) Chief Engineer James Singh, of the U.S.S. Saladin, has his hands full maintaining a stable warp field on a single-nacelled starship. Fortunately, he has a Doppelganger Warp Drive which uses a specialized tractor beam to simulate the field created by a second nacelle. DWD invented by my friend G.S. Davis, who has a comic set aboard a sister ship of the Saladin, which can be found at www.usstamerlane.com, featuring, yes, you guessed it, the Destroyer NCC-510, U.S.S. Tamerlane. I heartily recommend the stories if you like Star Trek. If you don't... why are you looking at this picture? Ken :)
