Just before the plane enters on the last hangar (the one that doesn't open the door), throw some web on the back part of the plane (the part that makes the plane go right or left). Now, inside the last hangar, throw web on the left motor (facing the front of the plane) till it stops to function (the "red triangle" above the motor won't disappear). The plane will start to turn around the hangar. Quickly throw web on the other motor till the "red triangle" above it disapears. Finally, throw more web on the first motor till the "red triangle" above it disapears too.
