>granted, those were not official SpaceX statements From the Elon Musk AMA: Q: How will you secure the first stage of the Falcon 9 to the barge when it lands? Gravity or some mechanism? A: Mostly gravity. The center of gravity is pretty low for the booster, as all the engines and residual propellant is at the bottom. We are going to weld steel shoes over the landing feet as a precautionary measure http://www.reddit.com/r/IAmA/comments/2rgsan/i_am_elon_musk_ceocto_of_a_rocket_company_ama/cnfqgek?context=1 http://www.reddit.com/r/IAmA/comments/2rgsan/i_am_elon_musk_...
