In December, 1943, Alex Tremulis created his "Lady in Red" in a design competition for a super-sonic jet aircraft capable of plus Mach 1 speed. Pre-dating the Bell X-1 by several months, both Tremulis' design and the Bell design incorporated the vision of a "bullet with wings". Powered by four TG180 jet engines, at that time the top engine available, the Lady in Red also incorporated somewhat unconventional swept-forward wings and the Bonanza-style rudder/tail not seen until decades later.
