Bring a Beetom down from above and freeze it in position to extend the runway. Shoot it again then quickly go back up and grab the second Beetom. Keep a half-tile gap between the Beetoms and the runway in order to extend it as much as possible. This is possible without breaking the Power Bomb blocks, by having both Beetoms attach to Samus, roll through the crumble blocks, then shake off the Beetoms to separate them.
