There are a great many eyes on the sky, and you can’t hide stuff up there - even every secret military satellite is known and tracked - so something as substantial as a collision would likely be known about before it even happens, as ephemera don’t change without an input.
Thank you for the answer. I'm aware of the degree of coverage over land but I was wondering about the ocean side of things as well.
