Another observation. After the disaster with the Blackhawk-Airline mid-air with the Pentagon's very own shuttle service flights for big-wigs has drawn scrutiny, the helicopter traffic for med-evac air ambulance and other helicopter traffic has dropped down so low I can see the pilots faces. Apparently close attention at ATC is being paid to incursions into flight paths and glideslope.
Like when I lived just south of DFW in Arlington.
You could set a watch on the timing.
One day we were grilling on the balcony and noticing thunder clouds and wind. About 30 minutes we could hear the crash of a Delta plane because of a wind shear.
