Major airlines have two pilots and expensive avionics. But "commercial aircraft" refers to all aircraft with paying passengers, including Cessnas with a single pilot that take a few passengers sightseeing. As I said, fatalities are extremely rare in *any* of these flights.

And all pilots are guided by air traffic control, from major airliners to solo private pilots. Air traffic control is meant to prevent mid-air collisions, an air traffic control system that ignored small aircraft would be pointless.
