The Seattle Police Department is searching for two men who climbed over the glass wall of the city’s iconic Space Needle on Friday, jumped over the edge and parachuted from the 605-foot structure.

The jumpers face charges of trespassing, according to a report provided by Public Affairs Officer Brian Pritchard.

The BASE jumpers purchased tickets and entered the Space Needle around 8:50 p.m. on Friday, according to the Seattle Police Department. The popular attraction has a round observation deck surrounded by tall glass windows open to the sky.

They were seen on camera on the upper level of the Needle and then went into a bathroom and came out with helmets on, according to police.

They ran to the glass window, climbed to the other side and jumped, according to police.

Space Needle security was unsure where the men landed and police were unable to locate them. They have not been identified by authorities and were described only as white men in their 20s.

BASE jumping is an extreme sport that involves jumping from objects and deploying a parachute. It is an acronym for the platforms from which parachutists jump: buildings, antennas, spans (bridges) and Earth.

The Space Needle did not immediately respond to emailed requests for comment Saturday.
