WOW three times on the same booster ?? Way to go Space X !!
The upcoming booster ascent escape crew escape demonstration will be its 4th and probably last, I don't think they're going to try to recover it after the test. In which case they will launch it without legs or grid fins. The grid fins are very expensive, milled from a single piece of titanium I believe.
“Government has three primary functions. It should provide for military defense of the nation. It should enforce contracts between individuals. It should protect citizens from crimes against themselves or their property. When government-- in pursuit of good intentions tries to rearrange the economy, legislate morality, or help special interests, the cost comes in inefficiency, lack of motivation, and loss of freedom. Government should be a referee, not an active player.” - Milton Friedman
