Impressive line-up of ten Ala 11 Mirage III: three Mirage IIIDE (CE.11) and seven Mirage IIIEE (CE.11) being prepared for the air parade on the first Día de Las Fuerzas Armadas (Spanish Armed Forces Day) that have been approved by the new Spanish Government only 16 days before. Finally, only nine Mirage III took part in the event as one of the trainers had problems with the canopy and had to stay grounded. Serial of the one if the foreground is CE.11-29: some might think it reads CE.11-89 but that's an optical illusion due tho the fact its previous serial was CE.11-6.
