Flying while in the Marine Corps in a AD Skuraider & with a wing man, at apprx 6,000 ft observed Four Red cly objects estimating at 20,000. 11:00 O clock-radioed to wing man--He also saw it--decided to chase== As we gained alt to 18,000, the objects moved at a very fast rate & disappeared at approx 3 minutes--they were not in a Military formation--Course this was era when any Pilots reporting any such sightings were somewhat harrassed & sometimes released from the Military--after landing, asked my wingman what He observed and Stated, Nothing & I said nothing--Did not report it nor did I--Talked about it only till I left the Corps--ironic about this is that My girl had taken some pictures about that same time over a Hilly area & the pic had a Red dot image on it--approx 1 year later in the So Calif at a lake, observed 5 white objects approx 29,000 again, not in any Military formation scrambling in no particular order--on the late nite news someone filmed the same objects--nothing what said about it in any type Media after that--Do I believe in UFO s? Not sure, but?!
