Secret Scotland

If it's secret, and in Scotland…

Leonardo da Vinci knew a good thing when he saw it

I’ve already mentioned Leonardo Da Vinci: A Life in Drawing at Kelvingrove.

I probably won’t include any pics of the exhibits though, as the room has subdued lighting to protect them for damage by over-exposure to light. Maybe later, when it’s quieter. But the sketches are both small and very subtle, a result of the way they were produced by silverpoint, in which a silver-tipped instrument inscribes lines on a surface that has been coated with a ground or pigment. This was used for drawing used in drawing during the fourteenth and fifteenth centuries because it produced a fine line, and the sharp point was maintained in use.

But I came across an image of an earlier exhibition, The Da Vinci Experience, which took place in San Diego back at the end of 2009.

The pic makes it look as if da Vinci is looking (approvingly) at the A-12 on display just below his eyes.

Although most will identify the aircraft as an SR-71, it seems this is A-12 – 06933, on display at San Diego Air and Space Museum.

Briefly, The A-12 was a single seat aircraft, while the SR-71 (and YF-12) were 2 seat. The A-12 was shorter and lighter than the SR-71, meaning it could fly a bit higher and faster. Operationally, the A-12 was designed for direct overflight, with cameras pointing, straight down. The SR-71 was designed with oblique (side looking) cameras, avoiding the need for direct overflights.
