Appearance / Description of Object(s)

A disc-shaped object that with a shiny silver/chrome metallic skin that reflected the light around it. This object resembled a shiny helium balloon that can be bought at stores, only bigger. Surface of the ballon including the edges was perfectly smooth with no markings and no creases. Object was flying straight and true without any wobble whatsoever, and seemed to be self-propelled at approximately 100-150 mph East/Southeast towards Philadelphia.

Size of Object(s)

Approximately 8 feet in diameter.

Distance to Object(s) & Altitude

Object was 150-200 feet below my aircraft at approximately 8,000 ft altitude.

Full Description & Details

I boarded an US AIRWAYS express, turboprop flight from Philadelphia, PA, to Newburgh, NY, at approximately 8:00 p.m. Weather was a bit cloudy with a few dark rainclouds in sky. I had a window seat in the last row on the starboard(RIGHT) side. Plane took off and headed East/Northeast toward Stewart International Airport. Sun was setting low by the time we levelled off at approximately 8,000 feet. Looking down, I saw a white object that I at first thought must have been a bird. As I kept watching it, I realized it was an elliptical, disc-shaped object that only looked white since it had a shiny silver/chrome metallic skin that was reflecting the light around it. This object resembled a shiny helium balloon that can be bought at stores, except for the fact that it was on its flat side down and the suface of the ballon including the edges was perfectly smooth with no markings and no creases and bigger than a party ballon. The object had an approximate diameter of 8 feet, was flying straight and true without any wobble whatsoever, and seemed to be self-propelled at approximately 100-150 mph, in the direction from which we came. The whole event took approximately 3-5 seconds.

Can sighting be explained as any conventional man-made or natural object?

Possible to say it was a store-bought party balloon but I don't believe it would be flying at 8,000 feet straight and level at over 100 mph.

Witness Background

Active duty military with lots of distance estimation experience/training on the ground and in the air.

Views on UFOs, before and after sighting

Always interested in UFOs and always look out my window when flying. Still a bit skeptical without further proof but cannot explain the nature of the object if it was not a party balloon.
