At approx 1407, 7 Jan 48, Capt Carter was called by Lt Orner, AACS Detachment Commander, to come to Tower to witness an unidentified aerial object. Object appeared round and white (whiter than the clouds that passed in front of it) and could be seen thru cirus clouds. After observing it thru field glasses for some 3-4 minutes, he called Col Hix's office. Col Hix, Lt Col Wood & Capt Dusaler came to the tower shortly thereafter. Capt Carter then suggested that a group of P-51 aircraft in the vicinity be contacted to pursue the object. T/Sgt Blackwell, Tower Operator, contacted the flight leader to take a look. Three planes proceeded on a heading of approx 230°. One of the planes (Mantell's) spotted it at 1200 o'clock position. Another plane relayed "This is 15,000 ft. Let's level out" First speed as relayed by Mantell (180 MPH) Later, "object going up and forward as fast as 1 am" - or 360 MPH. Mantell then stated he was going to 20,000 ft and if no closer would abandon chase. Last radio contact heard by Capt Carter. NOTE: Apparently, Mantell blacked out at 20,000 ft or proceeded on since the object apparently appeared closer(if such were the case)and then crashed thru lack of oxygen. Does not seem to tally with report that the phenomena was "Venus or a comet"
