Sure, the military had lots of helicopters. Also, portable radios, intercontinental aircraft, and space rockets.
These were not a relatively affordable part of daily life, though. Now if I'm in a crunch, and the roads / subways get clogged down for some reason (not a rare event), I can theoretically quickly get from my office to JFK airport on a helicopter for $100 (more like $30 from 1968), if I share the flight with 3 other people. Also, for the same money I can get a half-decent RC quadcopter with a homing ability and a camera that spies from 1968 would kill for.
No flying cars, though. Blame air safety regulations.
