Jack and I could not see through the iced-up windshields and windows. We had to continue our descent to keep air speed above stalling. Through a small clear place on my side window I saw men running at full speed, and I also saw that we were about to touch down. I assumed those men were running from a building of some sort and we were lined up to hit it. Without any thought and perhaps with instinct, I pushed full left rudder that caused the airplane to slew around to the left and we touched down in a sideways attitude. The landing gear snapped off, the two outside engine propellers broke off and went cartwheeling across the airfield.
