It's difficult to answer the questions regarding angles & direction because I only saw it happen from inside my house & it happened so quickly. I was facing the living room windows on the east side of our house & saw a flash of light across the lower sky close to our house, which was similar to when lightning lights up the sky. This flash was then followed by a very bright white light that appeared to be falling straight down from the sky & then the light disappeared. I'm not sure exactly what direction it really came from due to where I was sitting in the house. I also am not sure if what I saw was the "terminal flash" but I did not see anything else after looking outside. It was amazing!!
