Combat operations begin in Operation Allied Force, the NATO air campaign against Yugoslavia. US aircraft fly about two-thirds of the 45,000 sorties, pressuring Serb leader Slobodan Milosevic to withdraw his forces from Kosovo.
The Air Force pulled a KC-135 out of storage at the “Boneyard” in early April, three weeks after another one of the service’s Stratotankers crashed in Iraq during Operation Epic Fury.
