No person transported by the owner or operator of any aircraft as a guest without payment for such transportation has claim for relief for damages against the owner or operator for injury, death, or loss in case of accident, unless the accident was caused by the gross negligence, intoxication, or willful and wanton misconduct of the owner or operator of the aircraft, and unless the gross negligence, intoxication, or willful and wanton misconduct of the owner or operator of the aircraft contributed to the injury, death, or loss. No person so transported has claim for relief if that person has willfully or by want of ordinary care brought about that person’s own injury. For purposes of this section, the word “guest” means any person other than an employee of the owner or registrant of any aircraft, or of a person responsible for its operation with the owner’s or registrant’s express or implied consent, being in or upon, entering or leaving the same, except any passenger for hire and except any passenger while the aircraft is being used in the business of demonstrating or testing. The sharing of expense does not constitute a carriage for hire within the meaning of this section.
