Jose Francisco Rodriguez was flying a Dornier 27 light aircraft of the Portuguese air force over the Castelo de Bode dam when suddenly, coming out of the clouds, he saw a dark object against the background of white layered Cumulus clouds, slightly to the right of his plane. 

Thinking it might be a cargo plane, he turned left and immediately radioed to see if there was any traffic nearby. The answer was no.

 As the pilot completed a left turn, an unknown object suddenly appeared in his eleven o'clock position "no more than six meters away". It definitely wasn't a cargo plane. 

The upper part, partially hidden by the cloud, was black, and the lower part seemed to have four or five panels. The object's diameter ranged from 13 to 15 meters. 

Suddenly it accelerated and disappeared from what the pilot thought was its original stationary position. Dornier began to vibrate violently and dived uncontrollably. Trying to regain control, the pilot pushed the wheel forward. 

The flight speed increased to 140 knots, then to 180 knots as the ground approached. Fortunately, control was restored when the plane almost "touched the treetops" and the plane landed intact with the pilot badly shaken. 

During the encounter, the directional electric gyroscope (connected to a magnetic compass) rotated strongly, and by the time the plane landed, it had deviated 180° relative to the magnetic compass.

Summary:    José Fransisco Rodrigues was flying a Portuguese Air Force Dornier 27 light plane over the Castelo de Bode dam, when suddenly, emerging from the clouds, he saw a dark object against a backdrop of white stratocumulus, slightly to the right of his plane. Thinking that the object was perhaps a cargo plane, he banked to the left and immediately radioed to ask if there was any traffic in the vicinity. The reply was negative. As the pilot completed a turn to port, the unknown object suddenly appeared at his eleven o’clock position “no more than six meters away”. It was definitely not a cargo plane. The upper section, partially concealed by cloud, was black, and on the lower section there appeared to be four or five panels. The object was approximately  13 to 15 meters in diameter. Suddenly it accelerated and vanished from what the pilot believes was an initial stationary position. The Dornier began to vibrate violently and went into uncontrolled dive. Struggling to regain control, the pilot pushed the control column forward. Air speed increased to 140 knots then 180 knots as the ground came nearer. Control was fortunately regained when almost “touching the tree tops” and the plane was landed in one piece. – with a badly shaken pilot. During the encounter the directional electric gyroscope (connected to a magnetic compass) rotated wildly, and by the time the plane landed it had deviated by 180° relative to magnetic compass.
