July 20, 1952; Andrews AFB, Maryland (BB)
At around midnight various people in the Andrews Tower were talking about flying saucers. At this time T/Sgt John P. Izzo went up to the tower and heard Washington Center call the tower on the intercom advising that they had 5 unidentified targets over the Andrews range. Nothing appeared on the Andrews radar. A/1C William B. Brady gave the statement that Airman Goodman called the tower at around 12:05 a.m. and advised for him to look to the south immediately. When Brady looked he saw an object like an orange ball of fire trailing a tail at about two miles south and one half of a mile east of the Andrews range. The object made a circular movement and then took off at an unbelievable speed. Seconds later Brady saw another such object that made an arc like pattern and then disappeared. Later, Capt. Harold C. Way reported that Washington Center called and ask if Andrews radar had a target 3 miles north of Riverdale. Way checked the radar and there was a motionless target at the place Washington Center had indicated. It remained for about 25 to 30 seconds and then disappeared completely. (MAXW-PBB11-1003-1011) Air Intelligence Information Report stating that ARTC had same target located in the vicinity which was located over Andrew AFB. A call was made to Andrews on the direct line and Washington advised Andrews tower of the situation Andrews reported visual sightings of 3 objects in the position indicated by Washington tower. This all was just after midnight (0005 to0030) (MAXW-PBB11-1003-1011).

Douglas Larson:
For the next several days the Air Force claimed that its radar at nearby Andrews Air Force base did not confirm the findings of the CAA radar.  Later, however, the Air Force reversed itself and admitted that the Andrews radar did pick up the objects fours hours after the first CAA report.
