I recall an incident a year ago where an aeroflot aircraft with a medical emergency was denied landing in the US and had to land in Canada. The reason given was that the flight had departed from Cuba.
I donīt remember the whole story, and I imagine that a medical emergency is not a bomb threat, but I remember reading in the papers that it is the US policy to deny landing to any aircraft, of any airline, coming from Cuba, even in case of an emergency. Is this true?
