SIGHTING: MASON CITY, IA

Witness Testimony

"strange flying objectI saw a few friends walking to the gas station so i left my home and caught up to them .. i caught up to them at the end of a road that goes on to the highway..i noticed a low flying plane about 100 yards away with one red light in the middle and flashing white lights on the sides.. right as i pointed it out to my friends and they turned their heads toward it, it came to a dead stop and the lights changed to just 2 lights one on each side..they said my mind was playing tricks on me, but i knew what i saw, it was very strange..because it somehow knew that i pointed it out and right as my friends look at it .. it stops and changes its light pattern.. anyways.. we sat there staring at it for about a minute and it shot north flying at a very fast speed.. there were 3 lights on it blinking very fast one after another.. me and my friend left my other friend and started chasing it.. we ran a few blocks and saw it in an opening above the trees.. it changed its direction and looked like it was coming toward us.. at this time it was just one big light.. it kept getting bigger and bigger.. so i figured it was getting closer to us.. it whent out of our field of view behind a tree and dissapeared.. we wondered where it whent and all of the sudden it came out of nowhere in the opposite direction of us(east).. it flew by very fast and very low to the ground heading north.. it flew like a helicopter but was silent.. and also very fast.. just above the trees.. it whent out of our field of view behind a tree and dissapeared.. we haven't seen it since..this is not my first experience with ufo's .. and its my friends 2nd experience seeing a ufo.."
