His plan: Velcroing a credit card, er, a launch pad on his back, telling the son to climb on, hovering then upon 10-9-8-7-6-5-4-3-2-1 count, the son would take off .
Their plan went on ...
The father and son walked to a grassy area, son hopped on the daddy's back, off they hovered, they RTH together. But when the daddy counted down 9 to 1, the son screamed "I'm too scared, daddy!"
They landed safely then walked home.
