What is the thickest airfoil ever used in an aeroplane wing for lift ?

I am curious...I recall B-29 had 28% thick airfoil in the root of the wing.

Could 50% thick be possible...would it bring anything...like weight savings ?

I am referring to the good old "tear drop" shape...which is supposed to be the slickest ever.
