1. This was a prototype aircraft .
2. Only 2 were built.
3. One is still on display.
4. This aircraft was proof of concept vehicle, of an idea that a different company had thought of during the previous decade.
5. The concept was a success.
6. But it was not put into production.
7. Since this aircraft was never intended to a production craft, an existing fuselage was used.
8. Twin engined.
9. Other countries also experimented with aircraft that could do what this craft could.
10. The home country of this aircraft developed at least a couple of aircraft to take advantage of the data gathered with this craft.
