12:05 a.m. Sightings continuing from previous night. Two F-16s depart for the ninth interception attempt. Previous attempts have failed to maintain radar lock. Eight minutes later the first radar lock on is obtained. At 12:19 a.m. Semmerzake and Glons lose contact with the target. At 12:30 a.m. the fighter AL-17 has a radar contact; lock-on lasts for 6 seconds and is then broken with a jamming indicator shown on the on-board radarscope; speed 740 knots. Ground witnesses see the F-16's pass through the center of the first formation. The second formation disperses - one point goes up - the others disappear. Two minutes after that Glons and Semmerzake both detect a high speed contact six nm from Beauvechain. Speeds are 478-690 knots. At 12:47 a.m. Beauvechain RAPCON watches a contact on its scope for 9 mins, confirmed by Glons radar. Further attempts at interception fail. Ground observers see the last of the phenomenon disappear in the NNW.
