Is the glass all going to be painted gray like most of the other a/c at Pima? I assume this is to protect the glass from the sun?
It would be to protect the interior from high temps.
To answer the questions that have come up:
Painting the glass does several things. It helps keep the temps inside the airplane down, it protects the interior from fading in the sunlight, and it keeps the plexiglas from fogging over. It also discourages people from climbing up on airplanes to look in cockpits. If the airplane moves indoors then the material we use can be removed fairly easily.
The planes are painted because the paint helps protect the underlying surface. On the B-36 the magnesium skins are particularly sensitive to water so we have no choice about this one. The primer isn't designed to be left exposed and it will actually fade and flake faster than the top coat will. The paint we are using now should hold up longer than some of the stuff we were using in the past. We are hoping for 13-15 years from all of our recent paint jobs. We'll find out in 10 years when the first ones we did with this system hit the 13 year mark.
I don't know right off hand what was wrong with the hatch. It wasn't that we couldn't fix it. We decided that it wasn't worth the effort since we have no intention of opening the cockpit for tours and there is another way in if we have to get inside. If the decision about tours changes at some distant future point then we'll fix it.
