About 29 Down Wreck
This is Hawaii's newest and latest wreck dive. This 15 meter Havilland plane was used by the Hawaiian Air Transport Service. Years later this plane was used in a Hawaiian Film called 'Flight 29 Down' hence the name. She was built in the early 1950's and sank as a artificial reef in 2007. Despite her bottom time, she has already started to gain new marine life and coral growth. She rests on a sandy bottom and penetration is allowed.

Dive Site Hazards

  • Deceptive Entry Openings — Openings may become restrictive inside due to angle, collapse, or corrosion.

  • Surge-Induced Internal Silt Shift — Internal surge can move silt and debris without direct contact.

  • Partial Overhead Environment — Many wrecks limit direct ascent even without full penetration.

  • Fine Rust Particle Silt-Out — Disturbed rust particles can rapidly reduce visibility.

  • Hidden Depth Variations — Complex reef topography can conceal depth changes, leading to unintended profile variations.

  • Distraction from Marine Activity — High fish activity can distract divers and delay depth or gas awareness.

  • Rapid Surge Direction Changes — Surge near reef structures can reverse direction quickly, pushing divers sideways into unexpected areas.
