Input: Consider Input: 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 fightersusually 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.

Input: Consider Input: Question: How old was the star of the first Green Hornet movie when it was released? Passage:The Green Hornet was adapted into two movie serials, 1940's The Green Hornet and, in 1941, The Green Hornet Strikes Again! Disliking the treatment Republic gave The Lone Ranger in two serials, George W. Trendle took his property to Universal Pictures, and was much happier with the results. The first serial, titled simply The Green Hornet (1940), starred Gordon Jones in the title role, albeit dubbed by original radio Hornet Al Hodge whenever the hero's mask was in place, while The Green Hornet Strikes Again! (1941) starred Warren Hull. Keye Luke, who played the "Number One Son" in the Charlie Chan films, played Kato in both. Also starring in both serials were Anne Nagel as Lenore Case, Britt Reid's secretary, and Wade Boteler as Mike Axford, a reporter for the Daily Sentinel, the newspaper that Reid owned and published. Ford Beebe directed both serials, partnered by Ray Taylor on The Green Hornet and John Rawlins on The Green Hornet Strikes Again!, with George H. Plympton and Basil Dickey contributing to the screenplays for both serials. The Green Hornet ran for 13 chapters while The Green Hornet Strikes Again! had 15 installments, with the Hornet and Kato smashing a different racket in each chapter. In each serial, they were all linked to a single major crime syndicate which was itself put out of business in the finale, while the radio program had the various rackets completely independent of each other.
