Is the Berlin airlift considered to be part of the Marshall Plan?

Nah, it happened after the Marshall Plan. I would consider it part of the "F* You, USSR" Plan.

No the Berlin Airlift was a response to the Soviet Military Siege of the City of Berlin. The Marshall Plan was a way for the civilians in Europe to rebuild their countries. The Berlin Airlift was the Allied Military response to an attempt by the USSR to get total control of Berlin and the promise to Berliners that they were not going to be abandoned by the West even if they were in the middle of the Eastern Zone. All the aircraft used were military and the piloits and crews were all military or reserve.

No. The Marshall plan was a plan to help Europe rebuild after WWII. The Berlin Airlift was a reaction to the Russians closing the border so no vehicular traffic could get through to West Berlin. The USAF flew non stop supply flights into Berlin, landing at 3 minute intervals 24/7, until the Russians gave up and opened the border.

The Berlin airlift was to keep the residents alive until a more permanent solution to the Soviet blockade could be arrived at. It was during the time of the implementation of the Marshall Plan, but was not part of the plan.

No, it was mainly humain help, not part of the Marshall Plan. The planes involved were called "Rosinenbomber" (raisinbombers) by Germans, because besides much needed heating material and food, the pilots dropped sweets for the children of Berlin. The Pilot Gail Halvorsen was the first who -without permission- tied chocolate to handkerchiefs and dropped them from the planes he was flying with. When his superiors found out about this, he wasn't punished, rather soon all Airforce Members and lots of American civilians collected chocolate bars, chewing gum and raisins to help with operation "Little Vittles". Citizens of Berlin still are having fond memories of the pilots who helped them during the beginning of the "Cold War" and did not forget the special needs of young children...

I don't think so--though the motivation was related. The airlift was a response to Soviet actions, not an extension of the Marshal policy

I would say no but part of the Cold War more generally.

yes
