I'll add an extra distinction for the 747--the airplane's design is patented
(ref. _Wide-Body The Triumph of the 747_, Clive Irving, 1993, endpages;
pat. #212,564.) The patent was issued 29-10-68. Two questions:

1) Given that the patent will expire soon (assuming it was renewed, it's good
   for 28 years from issue, right?) any bets on whether there will be similar
   design aircraft from other builders?

2) The patent for the 747 references another patent, #202,749, issued 11-65
   to "Holtby et al." Any ideas on what that patent covers?
