"There's no way I imagined this plane - it was so low it was virtually on top of me. It was white with no markings but it was definitely military, it just had that look.

"It had two rear engines, a big fin on the back like a spoiler on the back of a car and with two upright fins at the side.

It was a Falcon 20.

Well that makes sense. I didn't know of any white fighter jets that were unmarked in the AF inventory.

I'm from Baton Rouge and two weeks ago I was 50 miles north of here with a coworker picking up some pipe to build a corral and this Coast Guard Falcon passed overhead. It was approx. 8 to 1k ft and going like a bat out hell heading SW. Seen these guys working many times working well north of the Gulf Coast. Multimission?
