it would have been physically impossible for either plane to have seen each other
If one accepts that statement as axiomatic,
then the inevitable conclusion is that GA
pilots are in fact suicidal.
I've been flying for over 40 years now, and
instructing for over 20 years, and nearly all
the people I give dual to have really substandard
lookouts.
They spend their time looking at toys in the
panel (foreskin?) in VMC, which I find terrifying.
And the solution proposed here is ... more toys
in the panel.
To top it off, they rely upon their comm radio to
avoid collisions, by tacking on "All conflicting
traffic please advise" to the end of all of their
transmissions.
Yep, more toys in the panel. And more wordy
radio transmissions. That's what's needed.
Back in the old days, many (most?) pilots also
rode motorcycles, which breeds a certain level
of justifiable paranoia, especially in traffic in
the city.
These days, fewer and fewer pilots ride motorcycles,
which shows.
