What would DB Cooper do?

I found this funny sign on the wall of a drop zone that I visited.  What would DB Cooper do?  Well... he would jump out of the plane of course!  The most infamous skydiver ever on November 24th 1971 hijacked a Northwest Orient Boeing 727-100 (tail number N467US), extorted $200,000 and jumped out of the back of it never to be seen or heard from again.  Did you know that he actually gave the alias "Dan Cooper" not "DB Cooper"?  Somewhere during the initial media reports it was mis-reported as DB instead of Dan and it stuck.... and now you know ;)
