Most curious. what was the exact time? Did you see any movement and in what direction.
A few years ago if you remember, the ISS dumped some stuff, and produced a similar trail, however not as long as this. This almost looks ground based, but then again, it gets slightly dimmer at the horizon.
I dont see this coming from a metropolis either.
Things that make you go hmmm.
going by the length jet trail its way too slow to be meteor, looks like at least a 5 to 10 second exposure, being its moving its not a lighthouse.. I think they may be right its a rocket or some type of fuel dump or perhaps a satellite or space junk reentering but I would expect that to be faster also
