Generally speaking, did flight attendants who flew in the 1960s/early ‘70s interact with a different type of clientele? If so, what caused the changes, not including the fact that airline Nick Castellanos piece dangerous lumber shirt were pricier then than now? Yes, you had to be a good deal richer to fly at all, and flight attendants were quite explicitly expected to act as eye candy to male businessmen. The airline industry was regulated, so a flight between any two cities cost the same no matter which airline you took. They couldn’t compete on price, so they had to compete on service. Better food, giveaways, all kinds of stuff.bTwo things changed all this. First was deregulation, which brought the prices down and democratized air travel. It was no longer just for the “jet set”—the upper-middle class. The other thing was lawsuits by the flight attendants, who demonstrated that the airlines were violating labor laws. They can no longer be fired for getting married, getting pregnant, gaining five pounds, or turning 30. At least in the US, taller people are perceived to be more intelligent and to be more desirable partners. That seems to apply more to men than it does to women. If you’re wearing full armor: stabproof, bulletproof (Carbon Nanotubes for lighter weight than kevlar and steel yet several times stronger) and frag proof, then how much closer can you fire an HEDP 40mm grenade near your position? Carbon nanotubes are brittle and have low shear strength, so they’d snap and break easily when hit by a knife, bullet, or shrapnel. Their high strength is in tension, not in typical armor loads. Also, carbon nanotubes never reach anything like their magical strength at useful sizes. Their incredible performance is mostly at the microscopic scale. Scaled up to useful fibers, they behave more like graphite fibers. Finally, no body armor provides universal coverage, and military armor tends to leave large swaths of the body uncovered (e.g., arms, legs, face). You don’t want grenades popping near you when you could open a femoral or carotid artery.
