Less well known is the fact that within a year another very similar incident occurred on a plane out of Memphis, Tennessee. A David Cooper boarded a United 727 flight en route to the new Houston Intercontinental Airport, demanded and received $200,000, a parachute, and directed the plane be flown north from there to an undisclosed location. Somewhere over southeast Texas he disappeared from the plane and was never heard from again.
Shortly after takeoff out of Houston a warning indicator went on in the cockpit telling the crew that the aft stairway had been deployed. Minutes later the plane felt pressure bumps which were assumed to be caused by the stairway moving in response to Cooper's jumping. When the red warning light first came on at 10:15 PM the captain noted the location as N 30 22.588, W 95 23.268. The plane was traveling 200 mph bearing zero degrees due north (true). The pressure bumps occurred at 10:21 but the location at this time was not noted by the captain. Although forward momentum would cause a jumper to continue to travel in the flight direction, there was a strong wind from the north that night that probably would have blown Cooper nearly back to his jump point.
Like his predecessor, neither Cooper nor the money have ever been found despite repeated search attempts over the years and it is generally believed he perished in the heavily wooded area that night or shortly after from injuries and exposure. This page has been initiated as a public service to enlist the help of Houston area geocachers in solving the mysterious disappearance of David Cooper. If you find any evidence of his whereabouts please log a find on this page. Thank you for your cooperation.
Note: The coordinates at the top of the page are for Houston Intercontinental Airport and the boarding gate of David Cooper's final flight. You do not need to go there for any part of this cache.
I will require in your log a positive acknowledgement that you have found a PHYSICAL cache. I am getting too many dubious "finds" and I'm tired of asking each time. If you don't mention finding a PHYSICAL cache container and log, I will delete your log.
