Narrative:

Cleared by midway ground to taxi runway 31C, cleared to cross runway 31R. When just starting to cross runway 31R, aircraft X saw a jetstream aircraft Y at about 1/4 mi final to runway 31R (below 200 ft or so). Did not see him on first look. First officer was switching radio to tower at the time. When up on frequency, tower sent the jetstream around. Aircraft passed behind us. Ground, nor tower called us after the initial 'cleared to cross runway 31R' clearance.
