A reproduction of admittedly dismal quality of a Martin Co. painting of their December 1958 Dyna Soar configuration at launch. This configuration, the product of a team-up of Martin and Bell, competed against Boeing (and other companies) and lost; what must have been grating for the Martin-Bell folks was that the Boeing design that won looked nothing like the final Dyna Soar design… which actually looked a whole lot like this vehicle.
The Dyna Soar is here being shown launched by a modified Titan I ICBM. This booster would have fallen far short of orbiting the Dyna Soar; instead it would have simply tossed it on a long hypersonic suborbital trajectory. This would have been a purely experimental aircraft, the natural follow-on to the X-15.
