Yeah, like bows and arrows, spears, swords, horses, B47's S55's, B204/5, all good in their day but that was yesterday. That's why we aren't still training in B47's, a bl**dy good aircraft in their day.
Willys jeeps and GMC 6 X 6's were great transport too, but even if you fitted them with turbocharged 454 ci engines and glass instrument panels, they're still yesterday's kit.
