Détails:
A Douglas DC-3A passenger plane, NC25678, was destroyed in an accident near Chicago Municipal Airport, IL (MDW), U.S.A. All three crew members and seven of the 13 passengers were killed.
The airplane operated on a flight from New York-La Guardia Airport, NY (LGA) to Chicago Municipal Airport, IL (MDW) with en route stops at Philadelphia, PA, Allentown, PA, Akron, OH and Cleveland, OH.
The airplane descended through the overcast near Chicago Municipal Airport and the pilot reported they would have to circle the airport to clear his windshield of ice, which impaired his vision.
After clearing the windshield the pilot decided to land on the northwest runway. At an altitude of approximately 160 feet, the airplane stalled, fell off to the left, and crashed while in an incipient spin. The accumulation of ice on the leading edges of the wing had raised the stall speed.

Probable Cause:

PROBABLE CAUSE: "Upon the basis of the foregoing findings of fact and upon all the evidence available at this time, we find that the probable cause of the accident aircraft NC25678 (United 21) on December 4, 1940, was the failure of the pilot to exercise that degree of caution and skill required to avert a stall while approaching for a landing on the short northwest runway. A substantial contributing factor to the accident was the error in judgement of Captain Scott in choosing that short runway for his landing."
