1991 I wasn't building Baidarkas. Actually I flew over the Atlantic from Germany and then drove a car from New York City to Los Angeles and back, carrying my bicycle in the trunk and having a ride here and there. The lesson leant here is that it is easy to carry a race bike with you on an airplane... I just disassembled everything and put the pieces in a solid box, the largest parts were the wheels and the bare naked frame. The next pics show three airplanes I have seen 1991 and I found it interesting they were an aluminum frame, covered with translucent skin.

Skin-on-frame airplanes...
