The account
On 2 November 1982 Captain Júlio Guerra, an instructor on an aerobatic sortie near Alenquer, saw an object near the ground that rose and circled his plane at high speed; two other pilots joined and also saw it. The Air Force, under General Lemos Ferreira, released the reports to a civilian scientific team, which met in Porto in 1984.
The sceptical view
Witness numbers and details vary between accounts, and no instrument record exists.
