Concept Aircraft - 1970s

The 1970s were a fallow period of speculative aircraft models.  The long and brutal Vietnam War had turned the public's enthusiasm away from all things military, and a series of oil shocks combined with the growing environmental movement had combined to convince people that the future just wasn't what it used to be.  What spec aircraft kits that did manage to make it to market were principally re-pops of earlier kits.  And even then their packaging lacked the serious realism of earlier concept models.
