B10

B10 was upgraded with larger filters to address the problems B9 encountered during its boostback. Despite this, B10's boostback ended prematurely, once again because of ice ingestion. The booster lost aerodynamic control (probably because its hot-stage ring was torn off by aerodynamic forces) and exploded 400 m above the water (via its FTS) at more than 1,100 km/h.
