Question: Which US Air Force plane that was shot down in Yugoslavia is the fastest? Passage:An important portion of the 1999 war between Yugoslavia and the NATO coalition involved combat between the Yugoslav Air Force, which was the predecessor of today's Serbian Air Force, and the opposing air forces of NATO. United States Air Force F-15s and F-16s flying mainly from Italian air force bases attacked the defending Yugoslav fighters—usually MiG-29s, which were in bad shape, due to lack of spare parts and maintenance. A total of six Yugoslav MiG-29s were shot down in 1999, of which three were shot down by USAF F-15s, one by a USAF F-16, and one by a RNAF F-16. One aircraft, according to a Serbian documentary, was hit by friendly fire from the ground. Another four were destroyed on the ground. During the course of the air war, Yugoslav anti-aircraft defenses downed a USAF F-16C and an F-117 Nighthawk, the first stealth aircraft to ever be shot down in combat.

Question: Did the band that recorded Kiss Kiss Kill Kill ever release a live album? Passage:Kiss Kiss Kill Kill is the third album by the Danish punk trio HorrorPops. The cover and songs convey a cinematic theme (particularly those with repressed female protagonists and escapist themes, the obvious example being the track "Thelma and Louise"). The album art mimics archetypical B-movie posters, promising "Twelve Tales About Love and Murder... Starring HorrorPops". Only "Boot to Boot" doesn't conform to the film formula. Inspired by the rioting in Copenhagen that followed the destruction of the Ungdomshuset(Youth House), an anarcho-punk squat and self-managed social centre, by police forces in 2007. Of the album's sound, lead singer Patricia Day stated in the Hellcat review of the album that the band was started "So that we could play all kinds of music [but]... We really wanted to get back to the classic new wave feel that we love. And I think our excitement about these songs has made a hell of difference."
