To reduce drag even more, mechanics wax their planes to reduce drag from skin effect, a common practice even back in World War II. While shortening the wings reduces drag, excessively short wings make the planes unstable. Gore-Tex could make socks out of ePTFE, and they would keep feet dry. Sintered PTFE parts have densities of about 2.15 g/cm3; unsintered, unexpanded parts have densities of 1.5 g/cm3, but they can be as low as less than 0.1 g/cm3, with a porosity of 96%. Here's a little peek inside the bag of tricks these aviation hot rodders use to get the most out of their aging warbirds.

In this process, unsintered PTFE extrusions are first heated to anywhere from 35° to 320°C while held and restrained in a device that can stretch extrusions at rates varying from 10% per second to 40,000% per second. decided to take a crack at Reno Unlimited air racing. But in one industry sector the breathable polymer made a big splash: athletic gear, especially shoes. Teams use variable-pitch props to keep engine rpm and prop-tip speed constant. • The Pulitzer Trophy races were the vehicle for this to happen. The Reno Air Races, held at Stead Airport, an old Air Force airfield north of Reno, hosts races for more than just aircraft in the Unlimited Class.
