Oh wow, getting to correspond with Tomba would be a real treat.
From the June 2007 issue of Model Aircraft Monthly:
"On the morning of the British amphibious landings at San Carlos on 21 May, HMS Ardent shelled Goose Green airstrip in attempt to keep the Pucaras grounded, and the gunfire commenced just as two pairs of Pucaras were in the process of taking off, although only three made it into the air. These three were joined by a further pair and they spread out to look for the landing areas.
One of the first Pucaras airborne was A-531 which was forced to fly alone after it's wingman had failed to take off and this was the first to find the British troops coming ashore, but, as it ran in to carry out an attack, it came under intense small arms fire before being shot down by a Stinger missile (SAM) fired by an SAS patrol on top of a nearby hill. Luckily, the pilot, Capitan Benitez, used his Martin Baker ejection seat to good effect by parachuting to safety from only 300 feet and managed to escape to his own lines on foot.
Soon afterwards, one of the pairs of Pucaras also found British troops coming ashore at San Carlos and they too ran the gauntlet if intense small arms fire and missiles but survived to carry out a quick attack before concentrating on the observation post directing naval gunfire towards the airstrip at Goose Green, which they attacked with rockets. After leaving this target however, the Pucaras luck ran out when they ran into a pair of Sea Harriers. In the low level pursuit that followed, Pucara A-511, flown by Major Carlos Tomba, was shot down by the Sea Harrier flown by Lt Cdr "Sharkey" Ward [ FRS.1 of No. 801 NAS but I do not know which airframe] who made a number of firing passes using his 30mm Aden cannon before Tomba ejected to safety."
Now, the first thing you notice is that although a two place aircraft, in these missions the pilot was solo in the Pucara.
I would guess that the A-511 is somewhere between Goose Green, north towards Port San Carlos. I'd also guess it's been long since spirited away by souvenir hunters. That's a 30km stretch of pretty desolate country, looks to me.
Jeremias, where did you get those pictures? looks like a personal collection.
Bish if you can get a piece of the thing I'd be ever so grateful and would use it in my model display.
