Why would I need the D Plane to explain this? Sounds like simple geometry to me.
Well certainly. D-Plane is like I said before, just an explanation of impact using geometry. I don't know if it interferes with anything Homer claimed about impact. Seems like a lot of people are arguing it does though I have not seen enough actual information to know who's right or wrong. That's why I've never said Homer was wrong... yet apparently a few people here seem to think I did for whatever reason.
