Once again, I made it to the terrific Flight Museum in Seattle. Above you see a 6 bladed propeller on a reconnaissance plane from the Vietnam Nam War. An early model using “Stealth” technology of the day.
WW II era flight suit for gunners. Some fountain pen, and the rest rest in various Pitt Artist Brush Pens in a Rhodia unlined sketchbook.
 
 
Above you’d see the drawing kit do one of Boeing’s chief engineers and later executives. It was nice to see the celebrated engineers and designers all drew, some very regularly as children.
AS much time as I spend at the museum as a volunteer, I’ve not seen that drawing kit! I need to find it. Excellent drawings!
