they guaranteed that they would deliver a package from Torino
to Tokyo now in twelve hours and it will only cost you $2000

per kilo to have your parcel delivered. .. if you are lucky.

I am unable to talk about many more details of the National
Aerospace Plane because there is a lot of secrecy attached to
it and obviously it is a vehicle which not only can be a
commercial Vehicle, a socalled Orient Express, but also can of
course perform a military mission. I was very surprised again
to see one of my son’s publications called "Popular Science"
(fig. 7) which in the May edition of the last year contained
many more details on the National Aerospace Plane than I am
allowed to talk about. So I will have to complete my
presentation on the National Aerospace Plane at this point but
I would suggest that if you want many more details, as I said,
than I am allowed to talk about, look in one of the magazines:

"Popular Science" .

In addition to the use of Titanium in airframes, there is also
a lot of Titanium in an engine. Fig. 8 shows the advanced F 100
engine: it shows not the weight of Titanium which actually
flies in the engine, but the amount of Titanium which is going
into the engine as import weight. If we could replace the
Nickel base materials with Titanium we could reduce the weight,
and, as in the airframe, even more so than in the airframe,
weight is very important in the engine.

For every pound in weight that you can save in the engine over
the lifetime of the airplane it is worth about a thousand
dollars. For every pound in weight saved in the engine, because
of balancing effects, that is location of the centre of gravity
of the aeroplane, you can save another five pounds in the
airframe. 30 for one pound in weight saving in the engine,
there is a total of six pounds weight saving, times perhaps a
thousand vehicles in a fleet, and times however many pounds you
can save. Very big numbers if you can replace Nickel with

Titanium.
