I appreciate the art of it all... that was drawn a year before I was born probably.
When I was working at Boeing military air craft in Wichita KS...early 90's I had a small fill-in job to do and did the drawing by hand with the architectural type extended tails on the P's and T's etc lettering using a straight edge with some understated flourish. an art piece more or less on scratch paper... showing light perspective lines etc.
I did projects on and off for those guys for several years.
last time I was there, I noticed one of the project managers had the sketch on the side of his desk. (2 or 3 years later).
I got an 11 x17 limited edition print of the super sonic B-2 bomber signed by the crew while I was there they all signed it while I was standing there it was a mach 2 or 3 bomber, to this day the exact speed is secret.
They practiced take offs from a very short runway, and hit 45 degrees within a second of two of getting off the ground, then banked it wings vertical to the ground with a full test load of bombs on board... it shook the earth from half a mile away.. the most impressive thing I have ever seen.
.. I was retained to solve their 5 axis mill problem.. every spring and fall the scrap rate on the huge titanium wing bosses were out of tolerance... they were leaving the 8' x 3' x 5' billets out in the sun.. and they shrank during the milling process once inside and cooled with the cutting fluid.
They built air force 1 and 2 there, using green card labor, and ran the low voltage avionics in the same conduits as the 480 volt wing flap and tail section drivers.. the plane wouldnt get off the ground... but they saved $15 dollars an hour on the labor though.
