Authorities say a British tourist who was pulled from the wreckage of a fiery helicopter crash in the Grand Canyon has been upgraded to fair condition at University Medical Center.
They say 29-year-old Jennifer Barham had been in critical condition since the sightseeing helicopter from Las Vegas went down Feb. 10 on tribal land outside Grand Canyon National Park.
A UMC spokesman says the 42-year-old pilot remains in critical condition.
Three other British tourists aboard the helicopter were killed the day of the crash and two others died weeks later after being hospitalized.
A preliminary report by the National Transportation Safety Board says the helicopter made at least two 360-degree turns before crashing.
Aviation experts say that indicates the tail rotor wasn't operating properly.
