AIRWAY HEIGHTS, Wash. -

Today marks one year since KC-135 Stratotanker carrying three Fairchild Airmen crashed in Kyrgyzstan.

Capt. Mark “Tyler” Voss, Capt. Victoria “Tory” Pinckney, and TSgt. Herman “Tre” Mackey III, all lost their lives.

Today each of them were honored at a ceremony at Fairchild Air Force Base's Memorial Grove Park.

"One year ago collectively we were wounded by the sudden and tragic news of their loss, and I do certainly acknowledge this windy morning that those wounds can never completely heal, but we can in time be come stronger by remembering and emulating sell 77's crews strength.," said Col. Brian Newberry.

The ceremony included the unveiling of a monument, that included a five feet tall pillar engraved with the tanker and Shell 77. Around the pillar sits three benches with each fallen airmen's names.

Officials say the cause of the crash occured after the KC-135 went into a Dutch Roll. The nose moved side to side, while the wings went up and down. The Dutch Roll eventually cause the tale of the plane to fall off.

Officials say the crash was preventable and have taken steps to change training.
