On '''March 5, 1969''' [[Prinair Flight 277]] departed [[Saint Thomas, U.S. Virgin Islands]] for a flight to San Juan. Seventeen minutes after take-off, the crew contacted San Juan Approach Control. The approach controller on duty (a trainee) replied; "Prinair Two Seven Seven, San Juan Approach Control, radar contact three miles east of Isla Verde...maintain four thousand." The aircraft was actually three miles east of the Fajardo waypoint instead of the Isla Verde waypoint (which is located about 10 miles west of the Fajardo waypoint). Six minutes later the aircraft crashed in the Sierra de Luquillo mountains at an elevation of about 2400 feet; all 19 occupants were killed. The accident investigation found that Air Traffic Control was to blame.<ref>[http://aviation-safety.net/database/record.php?id=19690305-0 Aviation Safety Network N563PR accident page.] Retrieved: August 13, 2008.</ref>
