Narrative:
When approximately 50 NM southwest of gates intersection (approximately 150 NM down range of vandenberg AFB), about 20 mins after an air force missile launch, encountered omega and VLF reception anomalies. #2 omega went into dead reckoning, followed by #1 omega shortly thereafter. #1 omega went in and out of dr for several minutes. Then after about 10 mins both omegas returned to proper navigation mode. At all times both omegas showed good reception on at least 4 omega stations. Supplemental information from acn 97807. At all times both omegas should suspect us or russian secret stuff.

THEN AFTER ABOUT 10 MINS BOTH OMEGAS RETURNED TO PROPER NAV MODE. AT ALL TIMES BOTH OMEGAS SHOWED GOOD RECEPTION ON AT LEAST 4 OMEGA STATIONS. SUPPLEMENTAL INFO FROM ACN 97807.
