The aircraft would be kept at level flight at low altitude until the best climbing speed of around 676 kmph was reached, at which point it would jettison the dolly, retract its extendable skid using a knob-topped release lever just forward of the throttle (as both levers were located atop the cockpit's portside 120 litre T-Stoff oxidizer tank) that engaged the aforementioned pneumatic cylinder, and then pull up into a 70° angle of climb, to a bomber's altitude.
