A Montana witness is not convinced that an object that shot across the night sky on May 10, 2010, was an F-15, according to testimony from the Mutual UFO Network (MUFON) witness reporting database.

"It moved very fast for about five seconds, I thought it was a shooting star, but then it just stopped," the witness stated. "It did not have any flashing lights like an airplane, it just looked like a star."

The witness later learned on the morning news that the Montana Air National Guard was conducting a training mission in the area the night before.

Montana, May 10, 2010 - object shot across sky and stopped. MUFON Case # 23241.

At approximately 23:20 I went outside to have a cigarette, it was a nice clear evening and the stars were shining. I was looking at one star that seamed to be very bright to the west of me when what I thought was a star next to it shot off heading North East.

It moved VERY fast for about five seconds, I thought it was a shooting star, but then it just stopped.

It did not have any flashing lights like an airplane, it just looked like a star.

It continued to shine from its new location, I figured I must be really tired and just seeing things, so I put out my cigarette, went inside and went to bed.

This morning on the news I heard that the local police had gotten dozens of calls about a large explosion around 23:00 last night. The local radio station (KPQX) reported that the Montana Air National Guard had been conducting routine training maneuvers using two F-15 fighters over Havre with their afterburners on which created a Sonic boom.

They also said they would be conducting more training exercises over the next few days and that they were sorry, that they didn't mean to scare anyone and that they would try to make sure it didn't happen again. A Major with the MANG added that certain atmospheric conditions contributed to the sonic boom reaching the ground. I do not know exactly what it was I saw last night, but I promise you it was NOT an F-15.
