## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Forced landing, descent - emergency
  - balloon equipment,envelope - open (contributing factor)
  - aircraft preflight - poor, pilot in command (cause)
- On ground/water collision with object, landing - flare/touchdown
  - object - wire,transmission (contributing factor)
  - proper touchdown point - not attained, pilot in command (contributing factor)

## Analysis

AFTER LIFTOFF WITH THE DEFLATION PANEL PARTIALLY OPEN, THE FLT CONTINUED TOWARDS THE LANDING LOCATION. WITH A HIGH RATE OF DESCENT ESTABLISHED, THE PLT REALIZED THAT THE BALLOON WOULD NOT CLEAR THE POWERLINES THAT WERE AHEAD OF THE LANDING LOCATION. HE THEN PULLED THE DEFLATION PANEL CORD, AFTER WHICH THE BALLOON DESCENDED RAPIDLY. THE GONDOLA TOUCHED DOWN AFTER WHICH THE ENVELOPE FELL ACROSS THE POWERLINES.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
