Baby steps. They weren't sure if they could even fly a solar plane, so they figured that out first. Then they weren't sure if they could even communicate with the thing once it's up in the air, so they've just figured that part out. Next step will be to figure out if they can fly and communicate in different weather conditions. And maybe they won't figure that out, but at least they didn't "imagine it was useless" and not even try.
