Steel frame doors that disappear below floor level when in open position are being used on two airplane hangars at Garner Field in Texas to provide 20 1/2 × 100-ft end openings; doors fold into 5 1/2-ft deep trench; their construction calls for exterior covering of 30-in. wide, longitudinal leaves of sheet metal and these leaves are stacked side by side when door is lowered into trench.
