perfectly shaped triangle seen just south of I-70, north of whiteman airforce base, hovering over a farmers field.I was riding with my dad from kansas city to columbia, mo. We were on I-70 traveling east when I looked out my window, looking south. I saw a triangular shaped aircraft, and when I asked my dad what it was he said a B2 bomber. We were close to Whiteman Airforce Base so it seemed logical. I was sceptical though because it wasn't moving. It hovered over a farm field and barely moved. It looked like it was facing north but never advanced toward us. I didn't notice any lights because it was 6 p.m. When I first saw it, it was tipped so I could see the top of it, then it tipped back so I could see the bottom. It was a perfect triangle and completely silver. It wasn't very high off the groud and directly off the highway. I didn't hear any sounds from it. I stared at it for about 15 seconds or so because we were traveling at around 70 miles per hour and didn't stop. I'm from st.charles county, missouri. I'm a freshman in college. My dad is an electrical engineer.
