Ingrid Patigler, 66, disappeared with her husband Gerhard after their red, white, and gold V-tail Bonanza (tail number N7062N) departed Wolf Lake in Palmer, Alaska, on June 20, 2009, bound for Whitehorse, Canada. The last radar return placed the aircraft near Middleton Island, and another pilot reported seeing a plane matching its description heading northeast through the Nizina Valley. After that, neither the couple nor the airplane were ever located.

Authorities launched an extensive joint US–Canadian search: Alaska’s effort covered about 142,000 square kilometers, included hundreds of sorties by the Alaska National Guard, Civil Air Patrol, and National Park Service over 38 days, and Canadian forces conducted a 20-day search. No wreckage was found and the official search was suspended. The NTSB concluded the cause of the accident was unknown because the airplane remains missing.

The Patigler family mounted private searches, guided in part by a revised sighting that led them to focus on Skolai Pass in Wrangell–St. Elias National Park and Preserve, but those efforts also found no trace. Does anyone have information about the flight path, radar contacts, or private search activity in the Skolai Pass area around June 2009?
