Watch this video,Falcon 9 has paint and/or primer literally falling off, and you’ll that a good amount of the rocket has lost its paint and cork insulation. You will also notice small pieces of paint and cork insulation falling off the Falcon 9. Then, at 00:08, a much larger piece rips-off, falls upon a building next to the Falcon 9 with enough force to bounce off the building and continue on.
To his credit, Elon Musk, head of SpaceX, admitted that the cork was not bonded properly because there were not sufficient contraction joints. Still, we wonder what else they didn’t get quite right.
