What would be small and fun to me, would be the Bede 5 Jet. My first job with the FAA I working at St. Pete/Clearwater Tower (PIE) about 1974 and we had an airshow with the Blue Angels scheduled. The day before the show, I was working local when a Bede called for landing 5 miles south. We didn't have brite radar in the tower at that time, you only had your eyes. I told to report 2 mile final, when he reported I didn't see anything. He asked if he could make an overhead approach, it was runway 35 which is almost 10,000' so I told him to make right traffic report initial over the threshold. He reported and I still didn't see him, so he hit the smoke and it was like magic, a stream of colored smoke appeared and I told him to report break. He came around so quick it was like a blur, it was the fastest I've ever seen aircraft turn 180 and land. I was always surprised the Bede Jets never developed into a bigger fad, I guess being single seat and the price probably hurt sales.
