Scrambling jets to intercept planes that wander into no-fly zones is a regular occurrence at DCA (the military craft usually launch from Andrews AFB, or possibly a local USCG station for rotorcraft).
Not uncommon at other airports where POTUS is a regular, airports with other VIPs (NYC area), major sporting events (no fly around the Super Bowl stadium). DCA has a permanent zone, the others are temporary and communicated via NOTAM.
