If the group review process goes well, the next step may include some experimentation, market research, or prototype development.

The true character of Eurotra was eventually acknowledged to be in fact pre-competitive research rather than prototype development.

There was also at least one ground test airframe for static testing in parallel with the prototype 68001 development.

They also extend into prototype development and various display projects.

For the purposes of the current project, the two major criteria were computational feasibility and rapid prototype development.
