One of the workers hurt in a fall at the Nebraska Air National Guard Headquarters in Lincoln this week died Saturday morning.

Twenty-five-year-old Ryan Hitchler of Waverly died at Bryan LGH Medical Center West. He and 21-year-old Preston Gibson of Merriam, Kansas were critically hurt Tuesday after falling nearly 20 feet from a lift platform outside a hangar.

Gibson remains in serious condition. Nebraska National Guard spokesman Lt. Col. Bob Vrana said the pair were repairing a hangar roof when the accident happened.
