BOSTON — A New Hampshire man tried to bring a loaded semi-automatic handgun onto his flight out of Logan Airport Monday, transportation officials said.

Transportation Security Administration officers found the gun in the man's belongings when they went through the X-ray machine. The .45-caliber had a bullet in the chamber, and officers found another magazine with 13 bullets.

The man, who has not been identified but is from Hooksett, N.H., was detained and questioned by Massachusetts State Police.
