The Berlin Crisis of 1961 began with the Soviet Union building a wall between East and West Berlin. The Soviets shut off access to West Berlin. The Allies responded with the Berlin Airlift and the crisis was resolved.

Your question is vague, so the only crisis dealing with Berlin that I can think of would be the Berlin airlift. If this is the case JFK was not in office in 1949. He wasn't elected president until 1960. If you mean the Cuban crisis that is a different story.
