Balloonists See UFOs

Case 1...

On April 24 1949 a group of five balloonists had just launched a weather balloon in the New Mexico desert and were tracking said balloon with a special telescope.

Suddenly the person operating the telescope sighted
another object in the sky and alerted the rest of the group.

They all could see the UFO with the naked eye.

Case 2...

A year prior a very similar incident had taken place on the 5th of April.
Three balloonists in the New Mexico desert were observing a weather balloon when they spotted a UFO moving at a very high rate of speed.

It had a round shape and was white gray and goldish. It flew erratically across the sky and performed vertical loops for about 30 seconds until it disappeared.
