A light approximately mid-cloud level went across the sky within 15-30 seconds

I stepped outside to have a cigarette and was observing the weather, which was very cloudy, but with patches of clear sky visible, as well as several aircraft in the area. I looked N-NE and saw a white light, far too big to be from a plane moving at incredible speed with no sound at all. I pulled my phone out and went to open my camera to take photo/video of the incident but it shut down and wouldn't start up until the object had passed, headed S-SE. If I had to give a size of the craft, I'd say it was the size of a street light viewed from 50-100ft from my vantage point. The speed it was cruising was unprecedented, as it appeared to be moving several times faster than a fighter jet. The only problem was there was absolutely no sound emitted, which was what gave my first inclination to it being otherworldly. I tried to tell a few people, though I was met with the typical looks or criticism of seeing things or being nuts. I don't know if anyone else saw it, but if they did, I'm sure they were either as flabbergasted as I was, or wrote it off as nothing of importance.
