Although the small print commemorates women Air Force pilots of WWII, we know that they were actually Army Air Corp pilots since the U.S. Air Force was founded on September 18, 1947. ONLY ONE LEFT! Yes this LARGE shirt is our last one and it is made of 50% cotton and 50% polyester. So why would we publish a produce with only one left? Why would we charge UNDER $20 for our last one? It makes no business sense. But at Tailwinds we can't help showing you unique and cool products celebrating flight. That is our mission since 1986. So we ask one favor. If you call in please let us know that you bought the last one so we can remember to take this off the site.
