Therein lies the key Lynn! There are several very exotic materials that
could work fine, but are made of unobtainium.

Boeing and others are winding miles of carbon fiber onto mandrels to
produce big fuselages every day.
Bucky balls and Bucky strands can be purchased over the internet and are
produced when oil sludge is burned.
The price of Unobtainium is going down. The first peer review comments the
discoverers of Fullerenes got back when they published was from Bell labs (My
old employer) and suggestions and comments looked like two New York City
telephone directories. You can weave Bucky strands into a sheet so thin you can
see through it, and it's stronger than a sheet of 4130 .0015 thick. Remember
invisible aluminum from a Star Trek
movie? You can buy it now.
Could Boeing use a spar for the 747 that is 30 tons lighter than aluminum
and has no life limit for fatigue?
When you order a Camero body in carbon fiber from a circle track supply
house, it comes in a cardboard tube about 14" in diameter. Hood, deck lid roof
and 4 fenders in a card board tube. The paint job and the stickers will weigh
more than the coachwork.
I have been put into shock by a materials discovery only 3 times. At a car
show I saw two Porsche brake rotors on a table. Porsche used to use giant wheel
diameters to get a bigger contact patch, and allow room for brake rotors the
size of coffee tables. One of the brake rotors had a length of chain that would
limit how close it could get to the edge of the table. I said, "what's the deal"
He said "pick that one up first" (The iron version) It was heavy, about 15
pounds. No news there. Now this one. I picked up the one with the chain, and my
mind locked up. The chain snatched the rotor from my hand. The second
rotor is made of tiny aluminum balls suspended in a ceramic foam and baked in an
oven. Weighs 4 pounds. Nearly the strength of steel. The chain was because
people would pick it up and throw it over their shoulders, or drop it on the
floor.
Shows no wear at all when carbon brake pads are used. Do not fade even when
bright orange. If brake rotors then why not brake calipers? Wheels? 747 Brake
rotors? It will take 100 years to get that past the FAA.
Never been done before you know.
The military has UAVs that look like mud dauber wasps that carry color TV
cameras.
What is next?
