About landing the Super Heavy booster, Wiki[1] says:

    > [S]hortly before landing,[67] it ignites its engines to slow sufficiently to be caught by two mechanical arms attached to the tower.

Does anyone know the reason to choose "two mechanical arms", instead of landing like the Falcon 9? And has SpaceX announced any plans to test these arms? In my mind, it sounds more wild to try to "catch" the landing booster with arms, rather than land on a pan. Anyone else?
