No, but I have friends who work at many of the places that make things that fly. The story about the flapping wings is early in a book called "Widebody" about the development of the 747 along with a bunch of other interesting pieces that put Boeing in the place that enabled them to do that, such as when the aerodynamic tests on the 243, the first plane with rounded surface at the root of the wing leaked to Douglas. Boeing built a huge windtunnel in the 1930s (very controversial at the time) but it was big enough for the empirical tests on the 747 wing (I think at 1/4 scale). When testing he 747 wing they found a flutter and corrected that by a little twist down at the outer end, which is quite obvious when you see one from behind at an airport.
Earlier this year I was on one of the last few 747 flights by United from SYD to SFO. We were greeted by the immigration computer having failed so they just let the airport fill up with about 3000 passengers and no-one doing anything. And even more amazing - in the home of free enterprise there was no enterprising person working the crowd as a drinks and snacks vendor! I bet that would have happened in Asia.

Good thing there's a pond between you and rAcer ...
The Boeing idea of flexing wings was a great idea for reducing stresses in the wings - which results in much better service life. Before the larger jets all wings were rigid, which results in more stress and weight.
