December 05, Miami, Fla. / Fourwind 192

At about 2040 eastern time, an amateur-built Fourwind 192 struck the Federal Reserve building in Miami. The two occupants, both pilots, were killed. The flight had departed Marathon, Fla., about 40 minutes earlier. As the airplane was transitioning north through the Miami Class B airspace and receiving VFR advisories from Approach, controllers saw it alter its course to the southeast without explanation. The controller failed to establish communications with the flight and it crashed into the building about three minutes later.
