From the cases I've seen, the guy on the ground was typically, but not always, at fault. The Udari Range incident is one where the pilot was in the wrong, and there have been night training missions end with guys on an OP being strafed because the pilot confused the IR pointer terminating at the target with the IR strobe placed on the OP. Altitude has had nothing to do with any of the cases we studied here at JTACQC, or that I've read about on my own.
DESERT STORM- A Marine LAV is out scouting for the Army. The JTAC that owned that area's airspace was never notified that the Marines had moved forward of the FLOT. Aircraft spot the vehicle and call it up. JTAC, going off the information available, stated "NO FRIENDLIES FORWARD OF FLOT" and cleared the aircrew. Several Marines were killed.
OIF- The event filmed by the BBC news crew. JTAC told the aircraft there was no time for a 9-line and went straight to a talk-on. Aircrew confirmed they saw a road, an intersection, and vehicles. The JTAC was taking fire from a position in front of him, but the aircrew were contact a position to his rear. The BBC position was never reported to the JTAC. Attack was cleared and the F-14 dropped on friendlies.
OEF- 2 x A1os attack an OP. A-10s had been prosecuting targets in the area for roughly an hour when the sun began to rise and the aircrew switched from NVGs to day visual. Target and friendly locations looked similar, and the A-10s rolled in on the OP.
OEF- JTAC fails to understand his equipment and passes a friendly grid to a B-52 for a JDAM drop. The JTAC had taken over from another JTAC that had already been conducting strikes for awhile. DAGR batteries die and when it re-initialized the JTAC passed the first coordinates that popped up, which were the friendlies.
Qala-i-Jangi_ F-18 drops a 2k pound JDAM on friendlies. Aircrew mixed up the friendly and target grids. Flight lead recognizes the error and corrects it in his system. Wingman fails to make the correction. Wingman reads coordinates back to lead, and lead again looks at the wrong set of coordinates and checks off on the drop.
