At the crossroads between A. Clark Avenue and A. Azimov Street in the old town, Primero's team tried to undercut Helio's car. In an open hatchway, three crew members began firing positron charges from a grenade launcher. But the Helio team began to direct their board to the ram. Pilot Primero twisted abruptly the steering wheel and one of the shooters fell overboard, tossing on a safety belt while the other shooters tried to maintain balance.
