Ufo sighting in Seabrook NH, March 29th 2016

I was outside smoking a cigarette & happened to look up at a star that's always out here but was blinking weirdly fast & unfamiliar tonight & out of nowhere a UFO appeared & glided across the entire sky in a matter of 3 seconds then just vanished, there's no way it was human related, plane's & jets don't even move close to that speed. It was unbelievable, I tried to get a photo or video but it was gone by the time my camera loaded/opened on my phone. I heard last week on the news that there's been several UFO sightings in NH recently. I don't know what's going on but definitely something, that was not a human craft!
