My 13 yr old daughter and I were returning home by SUV north, up Taulbut Road hill. We were just past the lacrosse box and almost at 14th when we both saw a bright electric white, with blue-silver tint, rectangular-ish mass appear about 45 degrees above the horizon (in front window) and descend quickly, straight down, below the horizon in about 3 seconds. It had a short fuzzy trail (not like a fireball) on the upward side and looked kind of like an electric sparkler all over the surface (like the EM drives on the ships in the Matrix movies). We waited for an explosion but there wasn't any sound, impact or smoke. The skies were clear blue but it was twilight and the sun was going down. It was hard to tell the size or how far away, but I'd guess it was the size of a small house. it looked like it landed somewhere north of where we were. I drove all the streets and checked all the parks north of Mission in the area I though it would have landed (between Cedar and Stave Lake Road, and Best and ?), and in that time the sun went down. There are lots of homes in that area. It could have landed beyond the farthest street, where there are lakes and woods, but I was also running out of gas and my daughter was a little creeped out, like we were in a horror movie, so we went and got gas and went home.
