## Probable cause

The pilot's pattern of poor decision-making that led to the initial launch, continued flight in fog and above clouds, and descent near or through clouds that decreased the pilot's ability to see and avoid obstacles. Contributing to the accident were (1) the pilot's impairing medical conditions and medications and (2) the Federal Aviation Administration's policy to not require a medical certificate for commercial balloon pilots.

## Findings

NTSB's coded findings; those marked are part of the probable cause.
