Fireball crossed sky and split into two objects

As a youth (1972-1974) I spent a lot of time on clear nights stargazing and looking through my telescope. I was familiar with constellations, planets, meteors, aircraft lights and traffic, etc. I observed the following unusual events on different nights:
1. A large fast-moving fireball came from the horizon to my left (from Trenton NJ) at a low altitude, quickly crossed overhead and just before going over the horizon to my right (toward Philadelphia) split into two fireballs. No sound. No trail. I was alone. I do not believe it was a meteor.
2. Witnessed a star-like light moving oddly and making right angles. My sister saw it first and pointed it out to me. We watched it for several minutes. No sound. No aircraft type lights.
3. Witnessed another star-like light moving oddly and at right angles. Attempted to look at it with my telescope. Instead of the dot of light anticipated, I saw something gray and black and out of focus. My perception was the object deliberately got into my field of view and was looking back at me. It immediately scared me, I did not try to focus, and I quickly went in the house. I didn’t use the telescope again for several months. I was alone.
