The Infrared Baron

“Can we improve upon the glorious The Red Baron?” growled Hitler to Göring,
Two weeks later, Göring’s scientists invented infra-red paint. Planes painted with it were totally invisible.
The next day, Hitler wanted a demonstration.
“A glorious day for the Reich,” he said. “I wish to see this invisible plane.”
A scientist whispered in Göring’s ear.
“What do you mean you can’t find it?” Göring hissed.
“Problem?” asked Hitler.
“The plane… just took off, fuhrer!” exclaimed Göring.
“Took off?” asked Hitler. “But I heard nothing.”
“Well…”
“Invisible and silent?” said Hitler. “Brilliant! The English will never know what hit them!”
