OMAHA, Neb. (AP) — Farewell, hangar queen.

Offutt Air Force Base’s 45th Reconnaissance Squadron said goodbye last week to one of its most trouble-prone jets, an OC-135B that logged 36,064 flight hours and 6,135 takeoffs and landings in nearly 60 years of military use.

“Jets get old, people get old,” said Lt. Col. Andrew “Tripper” Maus, the squadron’s commander. “Bittersweet’s probably the best word for it.”
