AAL121 (CDG-JFK) diverted to LHR; flight path glitch


#1

On Friday July 18, 2014, American Airlines flight 121 (N197AN), a Boeing 757-200, departed Paris (CDG/LFPG) for New York (JFK/KJFK) but encountered a problem shortly after departure and had to divert to London (LHR/EGLL).

The flight path for this diversion renders correctly except there is also a great circle arc from Paris to south Florida, tangent to runway heading at Paris.
