Authorities at Logan International Airport said the pilot of an American Eagle regional jet was worried his landing gear may have been damaged and aborted a landing attempt Wednesday morning, circling the airport with 40 people on board until he was able to safely land about 9:30 a.m.

The American Eagle plane first attempted to land before 8:20 a.m., officials said. The attempted landing was aborted after the pilot determined there might be a landing gear problem. The pilot continued circling until he could attempt a second landing.

"They tried to make the first landing. They took right off, circled around, did a few flybys to check the under carriage," passenger Bob Bowen said.

"He actually touched down and there was a 'Clunk' sound, and the plane lifted up again. That's not a good thing," passenger Bill Shannon said. "Everybody was very calm and collected, and the crew was unbelievable. The flight attendant was phenomenally composed."

"When he landed, he apparently felt that something was wrong and took off again," Logan spokesman Phil Orlandella said.

There was no confirmation of any damage to the plane's landing gear on a tower fly by.

The plane was identified as flight No. 4539 coming from Toronto, Canada. It was said to have 37 passengers and three crew members on board.
