Kurt Edward Ruppert, a 30-year-old experienced skydiver from Florida, went missing on January 3, 2013, after exiting a privately owned helicopter near North Bend, Washington. He was wearing a brown winged skydiving suit, a black helmet, and clear goggles and had about 1,000 jumps to his name. Witnesses in the helicopter and friends waiting at the landing zone did not see him emerge, and the pilot did not see a parachute deploy.

An extensive search of Mount Si followed. More than one hundred searchers from multiple teams covered at least five square miles over four days, but deep snow, wind, and very rugged, sometimes inaccessible terrain hampered efforts. Radar and cell phone data shifted focus to an area below the main trail, but that location produced no clues. The search was suspended when conditions and the low probability of finding him alive led teams to end the operation.

His brown and green wingsuit would have blended with the forest, and no trace was found. Does anyone who was in the Mount Si area that day or who has information about that flight have details to share?
