Narrative:

Iah departing on runway 15 with tailwind. Clearance to taxi to runway 15L. Taxied aircraft in ww hold pad to compute numbers for runway 15L. When ready; contacted tower and advised cleared to cross runway 15L; hold short of runway 15R. Started to cross the hold short line; nose over by maybe 10 ft. Aircraft crossed over and in front of nose of our aircraft. Believe it was an aerostar. Because of our position in the ww hold pad; we were facing toward the southwest away from the final when we started to move up. Could not see final clear until starting turn back on line up strip for the numbers. Could not and did not see propeller aircraft until he was by front of aircraft. Was not close to hitting our aircraft; but if I were faster on the taxi across or if aircraft landing on runway 15L was large; aircraft wold have been closer. Advised tower aircraft crossed in front of us and landed on runway 15L. Tower's comment was he thought the runway 15L was closed. Do not know if aerostar landed on wrong runway or what.
