In February 1967, the US DoD contracted Cavalier Aircraft Corporation to rehabilitate, remanufacture and modernize P-51D Mustang airframes for military use, under the Military Sales Program. Six of the refurbished aircraft (designated Cavalier Mustang II, and possibly allocated with 67 and 68 fiscal year serials) were delivered to El Salvador (four in September and two in December 1968) and registered as FAS 400, 401, 402, 403, 404, and 405. On October 9, 1968, FAS 402 was destroyed during a take off accident
The FAS Cavalier Mustang IIs had no USAF serial numbers, as they were not part of the MAP (e.g., not purchased by the USAF then given to the FAS). They were only ever identified -- including while they were being built by Cavalier -- as their FAS IDs. I have a few photos from inside the Cavalier hanger while the airplanes are in differing states of construction, and each of them has their FAS number stenciled in black paint on the bare metal fuselage.

Having lost one of their Cavaliers, an unarmed P-51D owned by Salvadoran entrepreneur Archie Baldocchi was “confiscated” and rapidly pressed into FAS service as ‘402’ (a duplicate serial), however, it is uncertain when this actually took place. During my research, I disclosed conflicting reports about this aircraft, one of which suggests that by July 14th it had no armament, which is unlikely to say the least.
Archie was a close "friend" of the FAS and the owner of YS-210P which became the second FAS 402. To say that the airplane was "confiscated" is probably an over-statement, as it implies that it was stolen or taken without the owner's consent. Archie was very closely involved with the operation and maintenance of the FAS Mustangs, and I have to believe that he likely willfully allowed his P-51 to be conscripted back into military service for his country.

By July 14th, the FAS had five Cavalier F-51Ds and one North American P-51D, although some sources have suggested that a couple of P-51D acquired and flown by “hired” USA pilots may have been in service. This has yet to be confirmed and perhaps Randy could shed some light on the matter.
They had Cavalier TF-51D FAS 400, plus Mustang IIs FAS 401, 403, 404, and 405, plus two stock Mustangs, FAS 402#2 (ex YS-210P) and FAS 406.
The three American mercenaries all flew Cavaliers -- FAS 401, 403, and 405 -- which the FAS Commander had allowed them to take as their personal aircraft during the week of the war. The two other mercenaries, Red Gray and Jerry DeLarm, flew other FAS Mustangs, of which there were at least three (FAS 404, FAS 402#2, and FAS 406). I doubt that Gray and Delarm were given 'exclusive' use of any of those aircraft, as obviously FAS pilots flew numerous combat missions in the Mustangs, too.
The 'illegal' P-51s purchased from the US did not arrive until midway through the week of the war, and were probably not ready for any sort of combat until after the ceasefire had all ready been signed.

The fact that the hired USA pilots did not acknowledge such collision having taken place at Ilopango airport (accident which the Cornejo book mentions on page 182), is most surprising
The mercenaries didn't even arrive at Ilopango until the night of the 16th, so they would not have been there for the collision itself, having happened that morning. The fact that they never mentioned it simply means that it did not involve FAS 401, 403, or 405, as those were the only three aircraft they had close involvement with, starting the evening of the 16th. They were largely isolated from the rest of the FAS pilots and airplanes for that week, and did not fly with or interact with them until after the war was over. Unfortunately, that isolation then also means that the Americans today can't fill in some of the details about the war because they didn't see some if it.

however, FAS 403 and 405 were based at Madresal island, one of half a dozen or so “satellite” airfields the FAS had activated before hostilities took place. Curiously, the Cornejo book publishes photos (pages 178 and 181) of such aircraft (serials visible) at that location “during the war”, but again, one never knows how accurate the information may be.
It's an overstatement to say that any of the Cavaliers were "based" at Madresal. One of the mercenaries recalls landing and re-arming there several times, but ultimately they always landed back at Ilopango at the end of the day.
FAS 405 had a landing accident at Madresal on the first day of the war, which resulted in an engine change at Madresal, and it might have stayed there overnight while that maintenance was being performed.

The Cornejo book is riddled with contradictory and inaccurate data, i.e., page 171 displays a photo of the remains of Cavalier II, FAS 402 (destroyed October 9, 1968), and incredibly on page 165, a photo shows “FAS 402 seen at Ilopango on December 1968” (the tail number is also visible).
Remember that there were two FAS 402s, so that is not at all impossible.

Although two of their pilots were KIA, all in all, they had at least two dozen pilots qualified in high performance aircraft. So the question has always been: why the need to hire foreign pilots (some of which may have not had previous combat experience)?
Probably because they wanted more good pilots!
Don't forget that Archie Baldocchi had been a warbird owner and pilot for years before the Soccer War. He was good friends and had flown with dozens of very talented Mustang pilots in the US (including the three who were eventually hired by the FAS). Archie had a lot of influence on how the FAS conducted business, and had been charged a month before the outbreak of the war to go purchase Mustangs in the US to augment the FAS fleet.
That is probably where the idea was hatched to hire American mercenary pilots to help out the FAS. Your question about "why" -- when they had several qualified Salvadoran pilots -- would they hire Americans in itself is telling. I interpret that to mean that the FAS leadership was not completely convinced that their own pilots had enough of an advantage over the FAH pilots. My guess is th at they wanted outside help to MAKE SURE that they had the best air force. Smartly, they did not want a fair fight.
