This is a great account of seeing a UFO that had created a cloud. I too have seen such things twice, once over Rapid City, SD when four large glowing balls created perfect cloud tunnels that never broke apart or drifted away...all starting above my parking lot and disappearing over the horizon...then glowing balls the size of a B-1 bomber began going down each tunnel one by one every 20-30 seconds, each time starting on a different tunnel. That was the summer of 1989-1990. Saw about 25 of these before I was late and had to race to EAFB where I worked on B-1s & KC135s. Its a SAC base.

News states: 
It was the summer of 1966. Julia and her daughter Anne decided to go to the mall, as both were anxious to do some back-to-school shopping. Little did they know they would have a cloud UFO experience.

The two were driving on the highway from Corning to the Arnot Mall in Horseheads, and were headed to a Southern Tier area known as Big Flats.

Julia glanced up and noticed an odd-looking cloud in the clear, blue summer sky and alerted her daughter about the strange cloud. Julia said that the reason the cloud was so unusual was because it was a sort of “puff.” Anne described it further by saying it looked like a huge cotton ball.

“That cloud began to dissipate and as it did a large saucer shaped object became visible.” Julia said after she pulled the car off the road onto the shoulder.

The two women marveled at what they were witnessing. “If you were to hold a soda bottle cap out at arm’s length you’ll have a good idea how big it was as it hovered there in the sky,” Anne explained.

After watching it for a moment, it suddenly got bright and just vanished in the clear blue sky.

“I’ve never seen anything like it before that day and I haven’t seen anything like it since,” Julia said.

Both mother and daughter assured me they remember the UFO incident like it was yesterday. (more at source)
