UFO Sighting in Bronx NY, New York on July 12th 2015 – from Van Courtland Park 250th st. to about 207th st. Red and White object gliding, hovering then shooting off hover and gliding and deesending

I was on my terrace looking NE and saw a few planes then I saw red light gliding south then hover for about 10 seconds, then a plane was approaching from the north and the red light object started to quickly rise and glide south behind the building in front of me, the second and third videos were of the object as it appread south of the building. This happened about an hour ago. I'm attaching the three video I took with my I Phone. I am leaving town torrow for a week and won't be back until the 20th. P.S. Because it desended between buildings. I am thinking it could be a drone, but the distance it covered rules that out.
