Crash of the Savoia Marchetti SM 83 near Mogador (Morocco) on 24-12-1939. Envelop from Rio de Janeiro 20-12-1939 to Amsterdam with official letter and envelop from the Dutch Postal autorities. (VH -G 110B, not mentioned in Nierinck). The plane was hit by lightning in a severe storm near the Moroccan coast. All the crew and passengers were killed and only a small part of the mail was salvaged. Recovered mail from the plane is therefore rare. Recovered letters to the Netherlands are seldom seen.
