Narrative:

At iad we were cleared into position and hold for runway 19L. Then they cleared us for takeoff for the same runway. During climb out we were switched to departure without any comments from the tower or departure of taking off without a clearance. We were advised that the FAA is investigating the situation. Today (mar/thu/98) is the first notification we received in reference to this matter. I would have sent it earlier if I would have been advised earlier. Callback conversation with reporter revealed the following information: analyst learned from the reporter that the flight crew were notified that they were not involved as the incident occurred a day earlier with the same flight.
