Military Internal Correspondence

Santa Cruz, May 28, 1986
From : 1st Ten Av Kleber Caldas Marinho
To : Commander of the Lo Gp Av Ca
Subject: Report of the fact occurred on 05/19/86 (Monday)

The first eye contact occurred after THOR commanded 180°. The objective was in the position of one to two hours low, at this moment, by order of LINCE I approved the objective and started an attempt of approach in the bow 240°. At a certain moment, as my search had only been visual until then, I turned on my on-board radar and got a contact at 12 o’clock (which matched the visual) at a distance ranging from 10 to 12 NM. From then on, I just felt that the object was moving away and when the order to turn on the radar to search was already out of reach of 20NM. From the first visual contact on FL 170 until the last FL330 observation, the object went from one situation, one to two hours. low, to 12-hour high. At a certain moment when I started to observe the object again, because I had stopped fixing my vision for a few moments, to avoid any kind of night illusion, I was able to observe 3 different colors, green, red and white that pulsed, prevailing for […] the white.

Regarding the on-board instruments, the only one that gave any change was the HSI, as ADF was selected (with this selection the DME continues to indicate normally) and at a certain moment when already at the bow 240° at about 200NM in the water (where the DME window should already have the red flag) I got pointer indications of the […] object varying from 10 to 20° to the right and DMR indications equal to 35 / 36NM and on the back when already at the bow 70° o the same instrument normalized, with the red window appearing.

The items that most marked the mission were the following:

– After reaching 180° the eye contact coincided with Thor’s instructions.
– When at 12 o’clock and a little closer, the onboard radar received a plot with the same situation 12h, 10 to 12MN.
– From a situation of one to two hours it went to 12 pm, 10° high.
– DME indication when 200 MN is indicating 35/36 DME and the hand the ADF is indicating in the bow varying 10 to 20° to the right. / KCM – 1TEN AV- Jambock17.
