http://www.nuforc.org/webreports/070/S70525.html I saw this posting,and recalled a night in 1994.

I was driving a moving truck with 2 helpers in the cab.
we were heading home from Bakersfield after dropping off a load of furniture.
I saw a triangle shaped craft,at first glance I thought it was a helicopter crashing in a field across the hwy, as we got closer to the object it shot back over the hwy about a 1/4 mile in front of us off to the right side of the hwy.  Then it seemed to just hover for a couple seconds and then it came right at my truck (30 foot moving truck) I thought it was going to hit us head on.
As it got within 20-30 ft it went right above us and over the cargo box, the craft continued down the hwy at a low height maybe 25 ft off the ground and went back to the field i first saw it in.
we continued down the hwy as i saw the craft in my side view mirror I dont recall any sound from the craft.
I would have heard an airplane or helicopter flying that low.
I tried to stop the truck and pull over,but the other 2 guys with me kept yelling don't stop keep going lets just get out of here.
I was shaken by the whole event we pulled over a few miles down the road.we said nothing to each other at that time.
I asked them about the flying object we all saw 2 days later and they both denied seeing anything.
basic design of craft I saw that night.  triangle shape 3 very bright lights they lit up the entire hwy, the craft had to be atleast 20ft  and I still to this date have never seen anything move that fast with so much control, I did have one person over the yrs tell me it was a glider, I dont think so, whatever it was we didnt make it!
