As for the impending ADS-B deadline..., I've never seen a buzzard with a transponder attached to it! Bird strikes can ruin your day (had 2 over the past 50 years flying).
ADS-B,
I helped a pilot mount That
2k dollar widget last week.
He’s going to swap it between
2 aircraft.
I’m still not sure of all
the particulars.
Don't get me started on medical education!
