That's why I told you what I saw.
The speed sounds very similar.
Worked many nights and when I was younger, went bass fishing at night and frogging in the marsh.
Never saw anything strange or unexplainable in the night sky.
This was weird. Can't say what it was other than a spot of bright light that hung stationary for a good while then hauled ass like nothing I have ever seen before or since.
Still kick myself for not going get the scope.
