if CTA was E 1500 here, the two IFR would never have hit at 4000 Would have been separated instead of self separating using traffic info. Surely the time has come to protect IFR to the capability of the system and for all aircraft to fit technology to be seen by ATC and each other. The skies are going to fill up with more LSA and drones so time to see and be seen with technology not just your eyes looking outside.
