The hero pilot who miraculously guided his crippled jet into a textbook landing in the icy Hudson River was a straight-A student as a schoolboy in Denison, Texas — but his school district gets an "F" for making his academic records public.

Ace pilot Chesley B. "Sully" Sullenberger III was in seclusion Friday, a day after he saved the lives of 155 passengers and crew aboard US Airways Flight 1549. But America was learning much about its newest hero — even his IQ scores.

Sullenberger, 57, led the pack even as a child, when he consistently tested in the 99th percentile in every academic category. His IQ qualified him for the "genius society" Mensa when he was just 12 years old.

But his official records were never meant to be released, and the Denison school district is now scrambling to recover the confidential documents that brought the private pilot even more into the public eye.

"I don't know how that got out of the district," said Cavin Boettger, Denison High School's principal. "That was an accident that was not intended to be released."

Sullenberger has retreated to his home and not spoken publicly since his splash landing saved 155 lives Thursday in a piece of flying that New York Gov. David Paterson called the "miracle on the Hudson."

When he emerges from isolation, he may have some explaining to do. The straight-A student missed 45 days of school in the 1st Grade.

Boettger said his district keeps all records in secure storage, so even 50 years after the fact they still had the facts on file. "We have to keep every transcript of every student ever," he said.

The records became public when they were scanned along with a childhood photo that was pasted to the transcript. "It was just a scan to get the photo, and then somehow that got out," he said.

Boettger, who was shocked that the files had been made public, asked FOXNews.com to delete them. Though he said he didn't know who could have made the mistake, he said he was on the case. "We're gonna try to find out who released that and who it was released to and how we could retrieve it," he said.
