I already thought my pa was the best dad in the world and then he dropped this beauty nugget on me...
Fast jet canopies are usually made from perspex and on the Tornado the canopy is particularly large and very expensive. The canopy has to be kept very clean and clear of imperfections. Scratches are polished out using an extremely fine polishing sheet called 'Micromesh'. This stuff is so fine it feels completely smooth to the touch but has different coarse standards indicated by colour. A scratch would take days to polish out leaving the canopy perfect again.
But here comes the beauty portion of this tale...After it had long been used as a military tool, 'Micromesh' was later adapted into nail buffers. Yes those little sticks that women carry around in their handbags to maintain smooth and shiny nails were developed from military technology, good eh?'
Who knew? Sx
Always on hand for an interesting technology fact!!
