a constant course, he realized it was not a skyvriter. Approximately ten to rifteen
seconds later, he called the object to the attention of his Flirht Leader, “ajor
Seville. Najor Sebille. Major Sebille then started a turn to the right, at least a
standard rate turn or better, which took us approximately one to one and one half
minutes to complete 160° to 225° of turn which put us oa a course to mrallel that of

the object. «then the turn was started undersigned officer estimted the distance of ;

the object to have been at least five miles to the South and approximately twenty
(20) miles away at an altitude of 15,000 to 20,000 feet. Upon completion of that turn!
the object appeared to be approximately 30,000 to 35,000 feet, still climbing and
ahead of the Plight about twanty (20) miles on a course of about 340°. The Flight
paralleled the course of the conetrail ani the object continued to climb and make us
look like we were standing still. It appeared to undersigned officer that it leveled .
off between 490,000 and 50,000 feet, north of us. There was a definite break or
“elocw” in the con—-trail when the object leveled off. ‘The con=trail could be seer:
from the top of the cloud level, estimated to be 19,000 feet to the objects level off
altitude. The trail was distinct and held, so that it tas still visible from the
ground after we had landed at 1220 hours. :

aerial gunnery tow mission and at anproxi:mtely 20 miles north of Clark Air Forse Snse,!'
at the altitude of 4500 feet, while on a southerly heading, undersigned officer
noticed a very dense conetrail in the vicinity of Subic Ray. ‘The con-trail was extenc=
ing north at a hijh rate of climb and speed. Undersipned officer could not clearly i
discern the object making this conetrail, From the time undersigned officer first suv |
this object until it disappeared up near the vicinity of Lingayan Gulf a matter of only
two or three minutes had elapsed. At Sirst sight this object appeared to be at an
altitude of about 15,000 feet and about 20 to 25 miles soutinest of Clark. This obdjecti
wag at an estimated 50,000 feet by the time undersigned officer lost sight of it. The
object appeared to be in level flight just before it disappeared from view.

At about 1200 hours, 8 Septecber 1949, undersigned officer was at the PX Service |
Station #4 at Clark Air Force Base, and spotted a vapor trail south of the field,
coming from the direction of Florida Blanca. Approximately ons and one hal! ninu tes
later the trail was far to the north. During the minute end a half that he watche
this vapor trail it did not appear to got wider from where he firs t% saw it to fiave

|} and passed over the west side of Clark Air Forces Base, whers it seemed to make a

_ slight changes of course to the left, appraximtely 10~, and continuad on in a
northerly direction. Undersigned officer could not tell whether cr not the vapor

| trail was changing altitude. It is hard to estimte the height of ths raper trail

| but it seemed to be above 30,000 feet. He could not see what caused the vapor trail.

' Where he saw the vapor trail make a slisht change of course, the trail appeared to

| burble for about ten seconds and remain in a burole state. Then the vapor trail
resumed it's straight unbroken form.

Le At approximately Q400 hours ZEBRA, & Septenbar 1949, five officer 4g the
67th Fighter Squadron, 18th Fighter Group, observed a con=trail climbing at 2 30
derres angle and at a high rate of speed in a Northerly direction. The object
causing this con-trail was not identified. Several of the observers saw only the
con=-trail and did not see what had caused said con-trail.

cr

2e Radar Jarning at the time of sighting was in operation aad was in the
process of calibration, using two F-51 type aircraft for’this purpose. The Fighter

mangas Controller on duty did not identify any other aircraft in the air at that

ime and is of the opinion that the con-trail wes formed by eaid two Pe5i aircraft.
This is discounted as thirty minutes time clapsed between the time of sighting and the
time these two aircraft left Clark Air Force Base at an altitude of 30,000 feat,
heading 360 degrees, and also only one con-trail was observed.

3. This section is unable to discern what object or phenomena caused the avova
mentioned con-trail. ‘
