.. An ill-considered landing.. cosmetic damage.
It was snowing.. the sun got in my eyes.. I heard a rattlesnake... my thumbs were on the wrong hands..
..Structures 101..
Typical in-flight buckling of unsupported leading edge sheeting on the Goldberg Electra. This happened in level flight. The fix is to add vertical shear webbing from the spar to the bottom of the end of the sheeting.
A serious arrival!
This is the AstroFlight Challenger after diving from a thermal Don't do that! The wings collapsed and floated free. The fuselage continued down..all the way down... Broke EVERYTHING forward of the trailing edge bulkhead in the fuselage.. The tail end of the fuselage survived, and flies again.. as does the wing. Another example of classic buckling... the ribs were sheared chordwise at 1/2 depth by the upper spar twisting into an "S" before it broke.
