Although the shuttle never flew from Vandenberg, Sikharulidze notes that it still could have made such a maneuver when returning from a mission in a 57-degree inclination orbit launched from the Kennedy Space Center. He does admit that such missions would have lost their surprise effect because the orbiter would not have been able to return to Earth after the first orbit and, instead of approaching Moscow from the south, would have had to overfly the entire country from east to west, giving Russian early warning systems ample time to detect it. For some reason, he singles out three shuttle missions that flew in 57-degree inclination orbits (STS-64, 68 and 99), but without specifically linking any of those to the alleged “dive over Moscow” (there were actually 20 shuttle missions that used this inclination.) Filin has usually referred to a mission in 1985, but has never specified which one.
