Plane?

Saw a shiny object move across the sky while on my way back home. It moved from right to left, and then faded within a second or two. It looked oval-shaped, moved quite fast (assuming it was quite far) and there was no sound. It flew along the abandoned air base. Regardless, I was pretty sure it was a plane .. until it faded. Might've still been a plane, making a sudden turn towards the abandoned base (away from me). There are aviation school students flying around at times.
