On May 2, 1999, 34-year-old Scott Croll was a passenger on a private Piper PA-24-260 Comanche, tail number N8694P, flying from Haines to Juneau, Alaska, with pilot David McKenzie. The last reported position was between Point Bridget and Mab Island, about 40 miles north of Juneau. The plane never arrived in Juneau and both occupants were never found.

The flight departed Haines around 11:52 a.m. under visual flight rules. Weather in the area of the presumed crash was reported as instrument meteorological conditions with rain and snow showers and clouds reaching the surface; another pilot noted that 1,100 feet appeared to be in the clouds. The Juneau Automated Flight Service Station had advised that VFR was not recommended due to reduced visibility in the canal, but the aircraft proceeded.

An FAA alert was issued at 1:22 p.m., prompting an extensive multi‑agency search that was suspended on May 6, 1999, with no wreckage or occupants located. The NTSB later recorded the probable cause as undetermined because the aircraft remains missing. Does anyone have information about the flight, sightings that day, or knowledge of the route between Point Bridget and Mab Island?
