It sounds like a bright meteor or fireball to me.
It's not uncommon to see various colours including green and orange, which are both very common.

And, no, green in meteors likely has nothing to do with copper. I wish people would stop repeating this misconception
and do some research
before posting.
Especially in the case of fast meteors, the green colour is usually at least in part due to oxygen. Leonid meteors, being very fast (for meteors) make
a great example:

It's also the case that a bright meteor will leave a persistent or "smoke" train, that usually soon dissipates/fades, but can linger on for a long
time in some rare cases.
Here's a short animation of a Quadrantid meteor and it's persistent train, taken by
Mike Hankey last year.
There are actually a few different types of meteor train/trail/wake - check
this link for the definitions.
Also, it's not uncommon to see a bright meteor or fireball that is not reported formally. They happen all the time.
Likewise - not every meteor is the same, and some can seem unusual. With so many variables affecting how a meteor can appear, that is not
surprising.
As for the smell, that may have been a coincidence, albeit an odd one. Alternatively, we don't have all of the answers when it comes to meteors at
this point in time. We know that they can produce a VLF signature which can cause an observer to hear simultaneous sounds along with the appearance of
the meteor it's thought. There might be a similar mechanism that triggers an observer to experience a smell - although I must admit I don't remember
reading a similar report like this in nearly fifteen years of reading them.
