I am a survivor of the BA2024 IAH - LGW on the 11th!!
On take off vibrations on the left engine could be clearly heard within the aircraft and the Capt imediately notified the paxs of his decision to return.
Shortly after smoke was within the cabin working from front to rear intensifying upon decent.
On clearing the runway the a/c was stopped and shut down immediately as the left engine was on fire.
Immediate evacuation followed using right shutes. One elderly pax was treated at the scene for shock the rest adjouned to the lounge for a large drink!!
Both crew on board and IAH ground staff were excellent though obviously there are learning points
