The vertically sensitive amongst should probably steer clear of the video above.
Video of three base-jumpers leaping from the top of the 1,776-foot tower at 1 World Trade Centre last September has finally emerged.
It stayed secret until now as it's rather incriminating to film yourself doing illegal things.
Unfortunately for Andrew Rossig and his three colleagues - two fellow jumpers and one lookout - police finally identified them in January and obtained a warrant to search for this amazing video.
The men claim "we just kind of walked in" to the tower and had not seen any security guards as they climbed to the roof at 3am.
The four turned themselves into police on Monday and will be charged with trespassing and burglary.
Only last week another incident raised question about security when 16-year-old Justin Casquejo walked past a sleeping security guard to climb to the top of the tower.
He was arrested after his descent.
