Well I remember when The Airshow would come to town the Blue Angles A4F's would overfly my house on practice runs..

The flight path for SR-71's going from Texas to Alaska went over my grade school. They flew supersonic so we heard 2-3 had sonic boom's a day from them..
I was 13 when I found out that not all jets make a double boom like the SR-71.. It's all I'd heard before.

Saw RC planes for for the first time when I was 7 at a Mall show.. I thought the one with the red servos was cool.. I think it was 1977
Later that day we went by the old Airport to watch them fly.. That was a cool day..
