Narrative:

After takeoff rotation; as we initiated gear retraction; we experienced a loud bang and smelled smoke in the cockpit. Tower called and reported hearing a loud bang and inquired if we were alright. All engine and cockpit indications were normal and the engines continued to deliver takeoff thrust. Our one jump seater was brought forward for assistance. We agreed the most likely scenario was a nose gear tire failure as the bang seemed to originate from directly below the cockpit. We contacted [appropriate operations personnel]. Unable to determine the nature of the problem we elected to return to [departure airport]. We declared an emergency and made an uneventful landing.
