Narrative:

I was the right seat passenger in cessna awaiting IFR clearance from jxn to det. Jxn tower advised there would be an indefinite delay. I was handling radios and asked to depart VFR and try to get our clearance airborne. Tower said to taxi into position and hold. The pilot started a left turn from the runup position to enter the runway and then braked hard to stop short as a twin landed right in front of us. If we had not stopped, the twin would have hit us. The tower seemed unaware of the conflict until we protested on the radio. I did not hear any landing clearance for the twin, but there was a good deal of radio traffic as 1 controller was handling clearance, ground and tower frequencys alone, and it was a busy sunday morning. After departing, on climb out, the pilot looked down at the twin that had just landed and told me the number was nyxz.
