It looks like some are seriously looking into altitude and historical weather pattern data... looking for clues in operational behavior. This is a daunting task. Good luck in your endeavors. Only time will tell if research into this matter proves to be revealing... or not as the case may be. Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks
