Flying home Friday afternoon, on decent, something caught my eye, 2 o'clock, same altitude, 2700 ft. Thought to myself, wow there's a bird at this altitude? Kept looking, waiting for it to move its wings or dive. Nothing. Dead level, and stayed in my 2 o'clock. As I got closer, it passed by my right. It was no bird, and the sun started to reflect a red color on its ...fuselage. I called Approach, and they asked more detail. Was about 5 miles from destination, and they were already giving warnings to departing aircraft heading north. The whole thing got my blood boiling. When drones first came out, it started to even bother my non pilot wife, just knowing some moron would get real stupid with a new toy. Well I guess this was my first brush with stupidity.
