Sorry for the late answer!
I am just now writing about the 1 May 82 combat and in contact with Brigadier Perona.
García Cuerva and Perona were not aware of the Lima missiles when merged with Thomas and Barton on 1 May 82.
They never considered that a missile could be launched at them from the front, and so Perona attempted a frontal cross with Thomas at the start of the air battle, eventually failing to aim guns. It must be said that Thomas attempted a frontal launch of a Lima at that crossing, but failed to get a tone.
Best!
