Most East Coast pilots are more familiar with flight restrictions involving Presidential travel, but a half dozen Los Angeles-area pilots will now become a lot more aware. The six were observed within Temporary Flight Restriction (TFR) airspace during President Obama's visit to L.A. two weeks ago, and directed by air traffic controllers to leave. The controllers filed reports with the local Flight Standards District Office, which is currently investigating. The pilots face penalties up to and including certificate suspension or revocation. The TFR affected flights near LAX, Santa Monica, Hawthorne Municipal, Van Nuys and Burbank airports.
