Since we don't have shots of Billy Dee saying how the Falcon is too damaged to make the shot, we have to think of other alternatives.

What if there were alarms in the cockpit and/or flashing lights indicating there is a serious problem with hull. Or maybe the additional crewman in the Falcon's cockpit could shout something about there being system malfunctions or a hull breach or something. Nein Numb could also be re-subtitled to carry on a conversation with other crew in the back.
