APO 729, U S Arny
= 4 April 1949
ist Sighting
"Altitude Be29 2500 feet indicated on pressure altimeter.
Light approximately 100 feet below. Approximately heading of B-29
45 degrees true. Approximate apparent heading of light 245 degrees
true. Intensity estimated as that of a 40 watt bulb at 200 feet.
Weather clear over the island at the time. 3/10 to 5/10 strate
cumiius clouds in the vicinity of the island. Visibility unlimited

2d Sighting
"Altitude Be29 5000 feet indicated and actual radar height.
Light estimated 1000 feet above. Heading of Be29 southerly on
north leg of range. Heading of light northerly. Same intensity as
Tirst sighting. Weather 3/10 to 5/10 strato cumilus clouds tons
to 5100 MSL. Be29 in the clear at the time. Visibility unlimited.
Base weather sent up an upper wind ballo on shortly after the
sightings. It was of the penlignt cell type. We were ona
southerly heading at the time and I picked out this light when
approximately 15 miles out, yet I did not see the "Licht" until we
were no more than 300 Lai from it. There was no resemblance
between the two lights. The pilot ballon light was bright and hard-
ly more than a pinpoint aA the other aca was dull and of a yellow-
ish ue and fairly large.
The pilot ballon was released from base operaticns and went up
in a slightly south easterly direction over the water and directly
ahead at our altitude while we were flying the north leg of the
beam. Yet the "light was north east of base operations by at least
500 yards on the first set hea Se
At both sightings the light appeared to be moving toward us at
a high speed."
