Narrative:

Immediately on takeoff, I was aware of an abnormal situation due to climb of aircraft and turns. I was at door 2R. Flight attendant in rear and middle of aircraft said they smelled terrible smell right as we took off. They called purser who called cockpit. Cockpit said their warning indicator light (fire) was illuminated. We were airborne in 4 mins. We were cleared for landing. Fire apparatus met flight and we deplaned at gate using jetbridge. Firemen boarded aircraft and questioned flight attendants at 3LR and 4LR. Myself and the flight attendant at 2L did not smell anything.
