Key Takeaways:

A low-time, non-instrument-rated helicopter pilot crashed into the Chesapeake Bay during a pleasure flight in foggy conditions after disregarding weather warnings and rental agreement stipulations.
The NTSB concluded the probable cause was the pilot's continued visual flight into instrument meteorological conditions (IMC), leading to an inadvertent descent.
The article suggests the primary factor was "lost horizon" disorientation, where the lack of a discernible line between gray sky and water caused the pilot to lose spatial awareness without adequate instrument training or cues.
The incident highlights the critical danger of spatial disorientation in marginal visual conditions, especially over featureless environments like water, even when technically within VFR limits for a helicopter.

In May 2019, two men took off from Tipton Airport (KFME) in Fort Meade, Maryland, for a pleasure flight. They were in a Guimbal Cabri G2 helicopter, and had hoped to find and photograph a relative of the passenger who was fishing from a boat in the Chesapeake Bay.

The morning was foggy; when the pilot called to file the flight plan required by the Washington, D.C., special-flight-rules area, the briefer reported that an airmet for possible IFR conditions was active until evening, and VFR was not recommended. When asked if he would like a weather briefing, the pilot replied that he did not need any other information.
