Turning pedantry into an art form, hopefully this will clear a few things up.
The Stinger incident was indeed relating to DSqn SAS returning from brassing up Goose Green on 21/05/82 in the vicinity of Sussex Mtn. The aircraft was a Grupo 3 Pucara (operating out of Goose Green) which was brought down after being hit in the starboard engine by the missile in question. The pilot baled out and returned on foot to the airfield. Despite a number of engagements, it was the only Stinger success of the war.
The aircraft claimed as being brought down by GPMG was one of two "possibles", both Skyhawks of Grupo 4. On 24/05/82, one Skyhawk crashed in King George Bay, West Falkland, after overflying San Carlos Water and being damaged by small arms fire and shrapnel. The pilot was killed in the crash. The second incident, a day later, occurred as a Skyhawk broke up in mid air after sustaining multiple hits from a variety of sources. The pilot survived in this instance.
There were of course many other aircraft damaged by small arms fire, but only these two confirmed as shot down by same.
No Mirage F1 were deployed by Argentina as the type was not in service with them. No Super Etendard overflew the Islands as they were indeed employed to sink aircraft carriers out at sea. The Mirage 111 and Israeli built Daggers of the FAA suffered no confirmed losses to ground fire. "Mike Curtis" a Welsh L/Cpl (promoted in the field) gpmg gunner in 5plt, B Coy, 2 Para who later had a distinguished career in 22 SAS, did indeed engage Skyhawks, but makes no personal claim to his downing the aircraft.
Aye.

Just because I look stupid doesn't mean to say that I'm not.
