This is what happened when a private seaplane operator attempted to get permission to take a New Orleans Times-Picayune photographer over the Gulf to document oil plumes:

“We were questioned extensively. Who was on the aircraft? Who did they work for?” recalled Rhonda Panepinto, who owns Southern Seaplane with her husband, Lyle. “The minute we mentioned media, the answer was: ‘Not allowed.’ ”

Journalists struggling to document the impact of the oil rig explosion have repeatedly found themselves turned away from public areas affected by the spill, and not only by BP and its contractors, but by local law enforcement, the Coast Guard and government officials.

Scientists, too, have complained about the trickle of information that has emerged from BP and government sources. Three weeks passed, for instance, from the time the Deepwater Horizon oil rig exploded on April 20 and the first images of oil gushing from an underwater pipe were released by BP.

“I think they’ve been trying to limit access,” said Representative Edward J. Markey, a Democrat from Massachusetts who fought BP to release more video from the underwater rovers that have been filming the oil-spewing pipe. “It is a company that was not used to transparency. It was not used to having public scrutiny of what it did.”

That’s from a very interesting New York Times story.
