The Chinese Space Program:
These are rocket cores that have been ballasted. They contain rocket fuel and nitrogen tetroxide. Highly toxic! They are allowed to re enter the atmosphere, however the Chinese are letting them fall in rural areas inhabited by communities...

Most rocket launches end up with the rocket horizontal
There is a maximum distance that you can see an object from based on it's size
Using that you can estimate the real angle the rocket is relative to straight vertical relative to the ground below it if the apparent angle is different because of the curvature of the earth & horizontal distance the rocket is from the observer
Accounting for that most rockets have a downward component to their velocity & do not go to space
