## Sequence of events

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

- In flight collision with object, landing - flare/touchdown
  - weather condition - unfavorable wind (contributing factor)
  - weather evaluation - inaccurate, pilot in command (cause)
  - wind information - conflicting, pilot in command (cause)

## Analysis

THE PLT STATED THAT THE WIND SHIFTED DURING LANDING AND THE BALLOON TOUCHED DOWN HARD AND LIFTED OFF AGAIN. WITH POWER LINES AHEAD A DECISION WAS MADE TO CROSS OVER BUT THE BALLOON STRUCK THE LINES. SEVERAL CABLES WERE BURNED THROUGH AND THE BALLOON WAS TORN NEAR THE SKIRT.
