I have flown many full size airplanes as a flying instructor for many years.
I have never seen a full size airplane carrying people that was covered with shrinking plastic film.
Not to stir the pot, but the vast majority of human powered aircraft, and many lightweight experimental designs make use of shrunk mylar film - in fact, the covering techniques are almost identical to that of using Monokote on an R/C model, with irons and heat guns. The only difference is that the film is first attached to the structure with double sided tape!
Below is the McCready designed "Bionic Bat", which used stored energy for competing in the Kremer Speed competition. The covering being used, I believe was 1/2 mil Mylar.
That's enough history for today, folks!
