Is it ‘bound to happen’? Sure, but over what time span? What are the odds that the number of satellites currently in space will have precisely the same altitude and will intersect with another’s orbit, at the same exact instant in time? How often would one expect one such an event? Maybe one was intentionally placed in the same orbit at some point, perhaps nefariously, and their relative closeness resulted in a collision, but I want someone smarter than me to calculate the probability and such before my suspicions will be put to rest that this is just a one in ? years event.

The first collision in space took place in 1996:
Cerise_(satellite)

You can see at around 1000km there is a lot of debris.
