Narrative:

The aircraft taxied for takeoff and all sounded fine until we started our takeoff. The engines didn't sound as if they were at full capacity. Once our wheels were off the ground, the aircraft made a loud popping noise and sounded as if the landing gear was having trouble. 2 passenger turned their call lights on and a deadheading flight attendant quickly responded and realized the right engine was on fire. The aft flight attendants advised the cockpit, and our aircraft soon headed back for ord. Callback conversation with reporter revealed the following information: the reporter stated that they were about 100 ft off the ground when she heard what she thought was the landing gear having trouble retracting. The 2 deadheading flight attendants saw the engine fire at the same time as the passenger. When notified of the engine fire, the captain did not tell them to prepare for an evacuate/evacuation, and they had a normal landing. They were met by in-flight supervisors, who were concerned of the emotional status of the cabin crew and the passenger and were later told that it was an engine backfire. They switched planes and continued on to their destination.
