Bird RADAR
I've already come to that conclusion. Get an old WX RADAR dedicated to bird watching at certain airports.
The DC-3s I flew in the 70s didn't have RADAR, however, we were often successful in getting the bored Center Controllers to tune their sets to paint weather when there was T'storm activity. At 2 or 3AM they didn't have much to do.
Occasionally, a controller was "too busy". I ended up flying through large cells on three occasions. All I can say is that the DC-3 is well built.
