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 involved. The FAA is peruing revokation of the
PRIVATE PILOT's certificate.
