Feb. 28 1994 over Bosnian skies, a USAF F-16 flown by Capt. Robert G. "Wilbur" Wright is firing an AIM-120 AMRAAM (Lockheed Martin illustration by K. Price Randel)
In accordance with the UN and NATO rules of engagement, orders to "land or exit the No-Fly Zone or be engaged" were issued twice but both warnings were ignored. While warnings were issued, the violating aircraft dropped bombs over their target. In such circumstances NATO has a "single key," meaning that only one clearance was needed, so the Combined Air Operations Center was immediately able to clear the F-16's to attack.
The Serbian Jastrebs headed northwards, back to their base. At 6:45 a.m., the NATO fighters engaged the planes. Captain Robert G. Wright fired his first AIM-120 AMRAAM, downing the first Jastreb which was flying at some 5,000 feet. The remaining Serbian Jastrebs dropped to a few hundred feet, flying at such a low level to use the mountainous terrain to hide from radar and make their escape back to Udbina. Capt. Wright pressed on, closing to within AIM-9 Sidewinder range. He fired two of his heat-seeking Sidewinder missiles, and they were seen to impact with the Serbian aircraft.
With his missiles all hitting their target but exhausted and low on fuel, Capt. Wright now handed over the chase to his wingman, Capt. Scott F. "Zulu" O'Grady, who had been flying top cover to his flight lead.
O'Grady dropped down to engage and fired a AIM-9M but it did not lock-on and missed. Black flight was now approaching "bingo fuel", the point at which a plane will not have enough fuel to return, so they pulled off to refuel from a KC-135 Stratotanker circling in orbit over the Adriatic. At the same time another pair of 526th Fighter Squadron F-16Cs, "Knight 25" and "Knight 26",[6] had been vectored to the area and took over the intercept by the AWACS. At 6:50 am, "Knight 25" managed to get in behind the remaining 3 Jastrebs. He launched a Sidewinder, downing another Serb J-21 Jastreb.
By now the Serbs were close to the international border and the F-16s had to break off the pursuit because the NATO was not empowered to engage aircraft outside Bosnian airspace. The remaining aircraft were able to land at Udbina Air Base in the Republic of Serbian Krajina in Croatia.
The USAF officially credited three kills to Captain Robert Gordon "Wilbur" Wright,[7] flying F-16C-40 #89-2137/RS, using an AIM-120 AMRAAM and two AIM-9 Sidewinders; and one kill using an AIM-9 Sidewinder to Captain Stephen L. "Yogi" Allen [8] flying F-16C-40 #89-2009/RS[9] of the same unit.
Capt. 1st Class Zlatko Mikerević[11] ejected probably near the villages of Bravsko and Crkveno, 9 miles west of Kljuc, survived
Capt. 1st Class Zlatan Crnalić[12][11] landed at Udbina Airport with his J-21 Jastreb Sr.nr. 24275 badly damaged, the aircraft later re-entered in service.
