Airport; Procedure
Momentary loss of control during takeoff. ORD ATIS indicated winds at 180/11 for our Runway 28R (full length) takeoff. Just prior to our takeoff ATC had cleared Aircraft Y to cross our runway and hold short of 28C; somewhere near mid-runway; if I recall correctly. While initial takeoff roll was uneventful; we had a sudden and aggressive yaw to the left which had me (as pilot flying) suspect we had an engine failure; but there was no loss of thrust. Aircraft responded well to corrective rudder inputs; but was destabilized by the event. Within second of the event we strongly suspected that the engine thrust of the freighter was causal to our sudden yaw to the left. Advised ATC upon being asked to switch to Departure frequency that we had concern over this event; but did not advise we would be submitting a report. However; given the possibility of far more negative consequences had the event occurred at a lower airspeed (such as if we had had an intersection departure); I now feel that a report is warranted to investigate the specific details of this event; and prevent a future loss of control on takeoff event which could lead to a hull loss and/or fatalities. Hold all heavy and larger aircraft facing runway so as to prevent engine thrust impact on landing and departing aircraft.
Large Transport Captain reported a Widebody Transport crossed runway he was departing resulted in momentary loss of control due to the Widebody Transport's jet blast.
