Intercepted NASA transmission describing alien spacecraft confirmed by reversed speech

On March 13th, 1989, Donald Ratsch, an American member of an amateur radio club that monitored all of NASA's space travel transmissions, recorded a message from the space shuttle Discovery indicating an alien contact.  The actual words were, "Houston this is Discovery, we still have the alien spacecraft on VFR".
 As a reversed speech researcher I was curious to see if the technique of slowing and reversing the recorded transmission would reveal whether or not the message was a hoax (as some claimed), a joke (as NASA claimed), or the simple truth.  In fact, the reversals indicate that not only is the message itself genuine, but the event it is describing was in fact taking place at that very moment.
 I've posted the audio so that others can enjoy this unique moment from 17 years ago.
