Question:

I saw a U.F.O. It was about four feet by three feet. The top half was red and the bottom half was yellow, like a light. It crashed into my window and then flew away. Was it an alien space craft?

--question from Ontario, Canada

Answer:

Alien space craft have been reported smaller in size than what a human could squeeze into and as large as eleven to fifteen miles long from what anonymous commercial pilots have described. So, whatever you saw fits into that size range. As to what you saw, it is important to recall what you heard, saw, or smelled at that moment, along with any behavior or thoughts which you experienced which were not typical for you. Did you have any witnesses? If so, what was their reaction? If you had any household pets, what was their reaction? Did the pets suffer any sudden sicknesses later?
