White & Green Zig Zag scheme. Note: the example shown is captured by the RAF however the only change is the roundels. So picture this with the Balkenkreuz instead
A single pen has 1.2 mL of ink, lets say you spend 0.2 mL for a single signature, that plus 35,000, would be 7,000 mL = 7 Liters = 7 kilograms (if we say a liter of ink weights 1 kilogram). So weights like less than 7 rounds of a .50 cal
For peeps who just want the info from the site
“On it’s trans Atlantic flight to England, the air crew found the B-17G was about 7 mph slower in cruise than a stock B-17G due to the extra weight of the paint used on the signatures and, also, the extra drag of the surface roughness from the thousands of colorful signature applications ! Both of these factors increased fuel consumption, which was also higher than normal, with the lower speeds of the plane, also less than normally forecast for a trip across the Atlantic, resulting in one of, 5 Grand’s, engines cutting out upon landing in the U.K. due to low fuel.”
