The team was in place and I had a 05:00 briefing scheduled at the Dive Center. It was time for me to get to work and research the aircraft. It's now 19:45 hours and I'm still not certain what type of aircraft we're recovering. I know it's a Cessna, possibly a 172, 180, 182, or maybe even a 206. I needed to know size, weights, approximate displacements, type of pontoons, wing and pontoon volumes, rigging points, area hazards, etc. This information will allow me to plan a more effective recovery. We pride ourselves in not doing any additional damage to the aircraft, vehicle, or vessel we're hired to recover. I have authored programs for the Professional Association of Diving Instructors (PADI) in underwater crime scene investigation, photographing potential evidence, evidence recovery, victim recovery, vehicle / vessel / aircraft recoveries to name a few. We've worked on a lot of "high profile" recoveries over the years and I know the value of documentation, photos, video, and preservation of evidence. We treat every recovery as a potential crime scene.
