I am a child of the 50's but my oldest son was born in the 70's. He would watch this show all the time and dressed up like the Greatest American Hero. He would "fly" and fall down everywhere.
When the show came out in DVD, I had to buy it and watched to see if it was as funny as I recalled. Yes, it stood the test of time. I laughed until my sides were sore.
I wondered if my son remembered his fasination with Ralph Hinkley. I wondered if he recalled how much it embarrassed his father, because he would dress up endless in the custom. When you took him out in public, he would "fly" and crash like Ralph. I went to my son's home recently and there they were, DVD of the Greatest American Hero. "But of course, he is still my hero." he said. For Ralph is all to real, he is the hero that can make mistakes and still be a hero.
