Triangle formation in sky above Tomball, Texas

A triangular formation of lights has been observed over the city of Tomball, in Harris County, Texas. On footage, recorded on November 8, 2013, we can see a UFO with three white and flashing lights.

Witness report:

Anyone know what these are?? 3 floating lights seen in the sky outside of Houston near Tomball, Texas around 8:30 pm on 11/8/2013. They were slowly floating towards the ground, but were moving independently of each other and frequently changed direction. Sparks were seen trailing behind them when they would move across the sky. And I am certain they weren't Chinese lanterns, because they were floating DOWN from very high in the sky (and they changed direction several times and had sparks trailing behind them.
