Caso Manises
On the night of 11 November 1979, a TAE Supercaravelle SE-210 operating flight JK297 from Salzburg to Las Palmas was forced to divert and execute an emergency landing at Aeropuerto de Manises (Valencia) after two intensely luminous objects paced the aircraft at extremely close range. Spanish air defence at EVA-5 (Aitana) tracked the objects on radar; two Mirage F1 fighters of the 11º Stormo were scrambled from Los Llanos Air Base. The complete Ejército del Aire file — including pilot statements, ATC transcripts, EVA-5 radar logs, and the AVA technical analysis — was declassified in 1994 under Orden 13/1992.
What the official record says
JK297 was at FL230 over the Mediterranean east of Valencia at approximately 23:00 local time when Cmdt. Lerdo de Tejada observed two red lights closing rapidly from the 10-o'clock position. The lights closed to within an estimated 500 m; at no point did they respond to standard interrogation. Declaring an emergency, the commander turned the aircraft toward Manises and requested a priority landing. The lights followed the diversion. ATC at Valencia confirmed visual contact. Spanish military radar at EVA-5 Aitana showed the contacts. Two Mirage F1s scrambled from Los Llanos at approximately 23:35; both attempted intercepts. One pilot — Captain Camara Pérez — reported establishing radar lock but the contact accelerated beyond F1 envelope. Both Mirages returned to base without visual confirmation.
Verbatim — Ejército del Aire conclusion, 1994 release
"Las observaciones efectuadas tanto por la tripulación del SE-210 como por los pilotos de los Mirage F1, así como las trazas registradas en los radares militares y civiles, no admiten explicación convencional dentro del conocimiento aeronáutico actual. El caso se cataloga como Fenómeno Aéreo No Identificado."

Civilian + academic follow-up
Spanish UAP researcher Juan Antonio Fernández Peris — formerly of Servicio de Información de la Defensa Aérea (SIDA) — led the internal review that produced the 1994 declassification package. The case is cited in NATO-level UAP review literature including the U.K. Condign report (2000) as a reference example of a multi-radar / multi-witness encounter in European airspace. The complete file is held at the Archivo Histórico del Ejército del Aire in Villaviciosa de Odón (Madrid).

Condign Report — European multi-sensor reference cases
UK Defence Intelligence Staff 2000 Condign report references Manises as a Europe-NATO-airspace multi-radar UAP case.
Why this case still matters
Manises is the first publicly-declassified case in any NATO state where a civilian airliner was diverted under emergency due to a UAP encounter, with simultaneous military radar + scramble + radar-lock corroboration. Spain's 1992 declassification programme — driven from inside SIDA by Capt. Fernández Peris — set the structural template that France's GEIPAN and Italy's Aeronautica Militare later adapted: publish the full file, leave findings unbinding, let civilian researchers and academics conduct independent analysis.
