YUBA COUNTY -- The Air Force has identified the Pilot killed in Tuesday's crash as Lt. Col. Ira S. Eadie.
The second pilot on board the U-2 when it crashed has not been identified but is expected to recover.
One day after the U-2 went down in the Sutter Buttes, the Air Force began a difficult investigation as it mourned the loss of a pilot.
"I can tell you this is a somber time, but our team is very focused on the mission at hand," said Col. Danielle Barnes, of the 9th Reconnaissance Wing at Beale Air Force base.
Col. Barnes says both pilots onboard the U-2 ejected and deployed parachutes.
Then came the difficult task of finding the pilots.
"Our emergency personnel responded on scene we did use ATVs and UTVs, utility terrain vehicles because the terrain there is very mountainous," said Col. Barnes.
The Sutter County Sheriff's Department is assisting the military's investigation into what went wrong.
"This is unique because its not often that you have an aircraft especially a military aircraft goes down," said Sutter County Undersheriff Jeff Pierce.
All U-2's are temporarily grounded at Beale after its first crash in about two decades.
"From our perspective the most significant loss is the loss of life and thats who we are focusing on now that family and their friends to make sure the are well cared for," Col. Barnes said.
The U-2 is widely known as the most difficult aircraft in the world to fly.
A donation fund has been set up to help Eadie's family pay for funeral costs.
