Vintage US Navy manual

Todd says: I think you'll dig these illustrations from a 1945 US Navy manual issued to pilots who were learning instrument flying techniques. Wonderful images, and it turns out they were designed by the General Motors Styling Section under the direction of Harley Earl -- the father of the tailfin.
And who was Harley Earl? Earl worked as a designer at General Motors from 1929 until 1959, where he rose to become the postwar chief of GM's styling section. He drew styling inspiration from airplanes throughout his career, and Earl's most famous design innovation was a little trick he cribbed from the swooping rear fins of the P-38 Lighting fighter flown during World War II. Earl adapted the design for the 1948 Cadillac, and in a stroke, he set in motion a "tailfin" craze that would continue for more than a decade. Before that, however, he put his staff in the service of the war effort, and "Flight thru Instruments" was created in response to a US government contract.Link

I had the unique and interesting experience of riding in a convertible Corvette in Hawaii with Jim Earl (Harley J. Earl's son) and Harley Earl Jr. (Jim's son and Harley J. Earl's grandson) while on a layover during bone fishing trip to Christmas Island. Jim and Harley Jr. are interesting, creative, thoughtful men, a pleasure to spend time with and great fishermen. It was a glimpse into the mind of Harley Sr. and a thrill.

Inertia is pointed in the wrong direction.
Nope, sure isn't. If you're trying to accelerate, which you would have to in order to climb, inertia resists that acceleration.
Once you're at speed, it helps keep you going. But given the context, it's an opposing force as pictured. (well, as drawn...)
Great illustrations, dated perhaps by Captain Power's huge grandpa underwear. So huge he needs a belt to hold 'em up.
Power is incorrectly conflated with lift, and lift is left out.
