BREAKING: @SpaceX confirms Booster 14 is being expended, in return for new Atmospheric Data & a 2 engine landing burn!
"The booster will attempt to fly at a higher angle of attack during its descent. By increasing the amount of atmospheric drag on the vehicle, a higher angle of attack can result in a lower descent speed which in turn requires less propellant for the initial landing burn."
"One of the three center engines used for the final phase of landing will be intentionally disabled to gather data on the ability for a backup engine from the middle ring to complete a landing burn. The booster will then transition to only two center engines for the end of the landing burn, with shutdown occurring while still above the Gulf of America and the vehicle expected to make a hard splashdown."
