Gulf oil disaster - A leak in a crucial piece of equipment may stall BP's effort to stop the massive oil gusher in the Gulf of Mexico. The equipment, called a choke line, started leaking Wednesday, another setback for the beleaguered company in its hope of stopping the disaster.

On the scene of the rig explosion - Mark Mead, Scott Russell and Bradley Shiver thought they were going to spend a few days out in the Gulf fishing for yellow fin tuna like they had done many times before.
They fish near the rigs because the fish are attracted to them. They noticed a light in the distance and something didnât look right. It seemed like a rig was on fire. They called the Horn Mountain rig to see if anyone knew anything. Before the rig could respond they heard a woman's voice. âMayday, mayday, mayday, this is the Deepwater Horizon. We are on fire!!â There has been an explosion and we are abandoning the rig.â
They were the first to arrive and will share their story with AC360 Thursday night.
