Narrative:

Our aircraft was cleared to taxi to the takeoff runway via txwys C and M which meant clearance to cross runway 30R en route to 30L. While approximately midpoint of taxiway C and runway 30R, the captain and I saw a light twin engine aircraft completing its turn to final and about to cross the threshold of runway 30R. The captain added power to accelerate across the runway as the light twin proceeded to descend to the runway. About the time our tail surfaces were clear of the runway, the light twin aborted his landing at about 15 feet above touchdown and went around. He may have had 100 feet vertical and 100 feet horizontal clearance from our tail as he passed by. Had he landed, our jet exhaust might have given him considerable trouble as he passed behind. Hobby ground control confirmed our clearance to cross 30R and also stated that the light twin had been told to go around twice by the tower prior to this incident.

Title: CLOSE PROX ACR LGT TAXIING TO TKOF LIGHT TWIN ON LNDG APCH.

Narrative: OUR ACFT WAS CLRED TO TAXI TO THE TKOF RWY VIA TXWYS C AND M WHICH MEANT CLRNC TO CROSS RWY 30R ENRTE TO 30L. WHILE APPROX MIDPOINT OF TXWY C AND RWY 30R, THE CAPT AND I SAW A LIGHT TWIN ENGINE ACFT COMPLETING ITS TURN TO FINAL AND ABOUT TO CROSS THE THRESHOLD OF RWY 30R. THE CAPT ADDED POWER TO ACCELERATE ACROSS THE RWY AS THE LIGHT TWIN PROCEEDED TO DSND TO THE RWY. ABOUT THE TIME OUR TAIL SURFACES WERE CLEAR OF THE RWY, THE LIGHT TWIN ABORTED HIS LNDG AT ABOUT 15 FEET ABOVE TOUCHDOWN AND WENT AROUND. HE MAY HAVE HAD 100 FEET VERTICAL AND 100 FEET HORIZONTAL CLRNC FROM OUR TAIL AS HE PASSED BY. HAD HE LANDED, OUR JET EXHAUST MIGHT HAVE GIVEN HIM CONSIDERABLE TROUBLE AS HE PASSED BEHIND. HOBBY GND CTL CONFIRMED OUR CLRNC TO CROSS 30R AND ALSO STATED THAT THE LIGHT TWIN HAD BEEN TOLD TO GO AROUND TWICE BY THE TWR PRIOR TO THIS INCIDENT.
