This is near impossible. Plane wings are designed to withstand plane weight multiplied to overload from moving with acceleration to up or down, plus considerations about wearing of materials (not important in this case, because plane was near new when disappeared). For this plane, considered overload, I think should be about 3.5 and wear overload about 2. Usually all these mean, when it was new, could do 4x and accepted to do aerobatics, but for survived now, I'm not sure if accepted straight flight with 1.5 overload :) Now imagine scenario, what NATURE force could do so delicate manipulation, so bent each wing to very similar angle, with 4x plane weight force and then stop? If you think, it was bent later, imagine scenario, how possible, near exact wear of each wing?
