Banja Luka incident
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-16s to attack.The remaining Jastrebs dropped to a few hundred metres, flying at low level to use the mountainous terrain to hide from radar and make their escape back to Udbina.O'Grady dropped down to engage and fired an AIM-9M; the missile locked on and a near explosion of the warhead triggered by the proximity fuse severely damaged the tail of the targeted Jastreb.Eight days later, on March 8, a Spanish Air Force CASA C-212 transport plane ferrying military personnel for UNPROFOR from Zagreb to Split was hit in the tail by what was reported to be a Soviet-made SA-7 MANPADS missile several miles east of Rijeka, near Serb-occupied Krajina.The tail control surfaces were damaged, the left engine failed, and four military passengers (from the US, the United Kingdom, France, and the Netherlands) were injured by shrapnel and splinters.[21][22] Though it declined to identify the perpetrator, NATO labeled the incident a "provocation", while Croat defence officials blamed "Serb terrorists" and claimed that two missiles were fired at the aircraft.
