P51guy and I are not dangerous. We have both grown up in the system we have in the USA and survived it.
In an ideal world, everyone would be on radar with radar seperation and a visual backup, and a TCAS system on top of everything.
Your examples are a bit weak. PSA/San Diego...both planes were under radar control, and PSA made a poor radio call of: we had him there a minute ago. From that tragedy planes under my command answer: traffic not in sight...vector us away from traffic.
Aeromexico over Los Angeles involved a piper which was flown by a poor man who had a heart attack and stumbled into TCA airspace.
And military helicopters, at night, over the ocean...well that is a unique operation involving brave men doing difficult things.
I've been in aviation for 35 years...P51guy more than that...and you sir?????
