Jason Hill, a corporate senior associate in the firm's office in Milton Keynes, England, died in the crash along with his younger brother, 30-year-old Stuart, and Stuart’s girlfriend, 27-year-old Becky Dobson. The Feb. 10 crash that killed Hill, 32, left critically injured two other Britons, including his own girlfriend, according to news reports. The pilot, Scott Booth, was also severely injured in the accident, which saw the EC-130 helicopter explode into a fireball after coming down in rough terrain. Rescuers and other first responders reportedly hiked into the area and reached the crash site by early evening Saturday, about a half hour after the accident. It took several hours to extract everyone from the wreckage, as rescue efforts were hampered by darkness and a storm that brought wind gusts of up to 50 miles per hour.

He previously studied law at the University of Southampton before completing his Legal Practice Course at the College of Law in Guildford, England. The National Transportation Safety Board has been tasked with examining the cause of the crash that killed Hill, his brother and Dobson. The sightseeing flight was reportedly operated by Papillon Airways and took off from a facility in Las Vegas. It went down near Quartermaster Canyon, located near the western rim of the Grand Canyon.
