THIS ^^ My curiosity got the best of me:
"According to official reports, the alliance suffered no fatalities as a direct result of combat operations. However, in the early hours of May 5, an American military
AH-64 Apache helicopter crashed not far from the border between Serbia and Albania.
[188] Another American
AH-64 helicopter crashed about 40 miles (64 km) northeast of
Tirana, Albania's capital, very close to the Albanian/Kosovo border.
[189] According to
CNN, the crash happened 45 miles (72 km) northeast of Tirana.
[190] The two American pilots of the helicopter, Army Chief Warrant Officers David Gibbs and Kevin L. Reichert, died in that crash. They were the only NATO fatalities during the war, according to NATO official statements."
