I thought they had green lasers to warn airplanes straying into the DC
ADIZ. Are they not operational?

This is the Visual Warning System (VWS). It was discussed in the NASA
Safety Newsletter.

My own take on it is that if a pilot is not communicating and doesn't
know where he is, he isn't likely to see the VWS or know what it means.
The CFI should have to redo all his courses and flying, i.e. requalify.

There was no CFI.

Anybody know what color the lasers are? I heard red and green which seems
terribly confusing. Red means stop, green means go. Not a good combination
in my book.
