I've got a scar across the bridge of my nose because of my wireframes. I was working as both an instructor and company mechanic at a small flight school, I needed to take some precision measurement of something on the engine, so I went to the toolbox, got a pair of calipers, and I was setting them up as I was walking to the plane, I ran slam into the trailing edge of the wing at eye level. Knocked my ass to the floor, and as I got up I realized I had blood running down my nose, because the wing had pushed my glasses into my face so hard the wire frame cut me.
Do you know what a static wick is? See, airplanes are prone to gathering static electricity, which will build up around the airplane and cause Saint Elmo's Fire. Which wasn't a problem back in the days of tall ships, it is a problem in the days of modern avionics. So airplanes will often have these antenna or frayed wire-like structures attached to their trailing edges to bleed off static electricity. And judging by the scratch I left on that wing flap, my eye socket missed one by about 5 inches.
