... You are worried that this light wing structure might not be strong enough to be safe. The article explains that an airplane can fly because the air exerts a force, called "lift," on the wings such that the lift is always perpendicular to the wing surface. ... To turn, the pilot "banks" the plane so that the wings are oriented at an angle to the horizontal. ... The article states that tests show that the new wing structure will support a force 4 times the lift necessary for level flight. ...
