Manhattan jury convicted three men who jumped with parachutes from the top of One World Trade Center in New York.

James Brady, 33, Andrew Rossig, 34, and Marko Markovich, 28 were convicted of criminal charges and are to be sentenced in August. The trios live in the New York City suburbs will face up to a year behind bars on the charges.

The jury found them guilty of reckless endangerment, reckless endangerment of property and unauthorized climbing, jumping, and suspending oneself from a structure. Although they were cleared of the most serious charge of burglary, they can face up to a year in prison.

Timothy Parlatore, a lawyer for Rossig said, "The district attorney's office has wasted a significant amount of time and a significant amount of taxpayer's dollars to turn a misdemeanor case into a felony".

According to prosecutors the men tiptoed through a gap in the construction fence at the then-unfinished One World Trade Center in 2013. They climbed from the top of the 104-storey at a height of over 500 metres to the tower's communications ring.

Brady, who was employed as an iron worker at the construction site, had previously hidden their equipment. The trio off the ring and parachuted down, one landing on the West Side Highway and the others in the surrounding area.

Manhattan District Attorney Cyrus Vance Jr said "Today, a jury found their stunt to be reckless and illegal. This verdict shows that the District Attorney's Office has wasted a significant amount of time and a significant amount of taxpayer's dollars to turn a misdemeanor case into a felony".
