100% the realest case you've ever seen. Would love to take a polygraph.

I witnessed one craft of a steady red appearance not flashing or pulsating.  Not a dark maroon red or a pale red just a regular inbetween red colour.  I was with my dad and a friend named Duncan when the sighting occured.  I witnessed the craft positioned above a factory named pang at the time of the sighting it was circular in appearance just a solid red glow.  It was disc shaped but slightly rounder than the typical disc you would see on one of those cliche tv programs that's so streamlined.   All I can say from the sighting is that the duration was approximately 15-20 seconds and what I witnessed I wouldn't describe as extra-terrestrial or a man made craft because at the end of the day who knows. all I know is what my eyes witnessed.  What I saw what the craft/disc shaped light I saw hover from a stationery position for about 5-10 seconds above the factory and then accelerate from a standstill to what I can only estimate as to be into the 1000's of mph's instantaneously without a whisper and then the craft disappeared behind cloud cover.  Like a bullet fired from a rifle, the velocity of the craft was astounding.  
My dad still mentions it to people to this day 10-11 years later as if it's a joke and kind of makes me feel uneasy and embaressed by what I'd seen.  If I could only guess at the speed of which I'm no expert I would assume to be 8-10000+ mph silently, instantly.  I live near Lakenheath & Mildenhall airbases's and see the harrier's on a regular basis and know they make a lot of noise when they accelerate.  I would be willing to take a polygraph or any test to prove what I saw be it extra-terrestrial or an experimental government craft, thanks for reading would love to prove what I had truly seen.
Witness indicates that the date is approximate.  PD
