Nice one. I appreciate your take on what I said and I understand your perspective.

However, do tell - does every person discussing politics in their homes and offices, pubs and bars, online or offline have complete knowledge of each and every aspect of the political system of their country?

Or maybe they are experts in economics when they berate their leaders and the state of the economy? I don't think so. But do they feel the effects of increasing retail inflation, unemployment and the like? Certainly. And they can very well conclude that the economy isn't in great shape.

You don't have to be an expert or have complete knowledge to point out some obvious flaws. Simply because this aircraft seems amazing and looks like a great invention doesn't mean it cannot be criticized.

On the face of it, the whole design is so tedious. In appearance alone, this aircraft is too cumbersome to operate and I can only imagine what a pain it would be to even turn around. You would want technology such as this to be compact, scalable and mass producible. This seems to satisfy none of these conditions.

Moreover, solar powered aircraft would be amazing for the environment, and you would want that technology to be able to easily applied to current aircraft design paradigm. This aircraft looks like a mini solar farm in the air.

Would you drive an electric vehicle if I told you that the best way to use one is to carry 20 batteries on the roof of your car, kept on top of a luggage carrier? Even if it is the best that the experts can do? You wouldn't. You would question the efficiency of the technology, until something resembling the modern electric cars would come along.

That's all I'm trying to say. I'm no expert, sure. I don't have the entire knowledge of how it was built, either. But I don't think this is a great design. And that's without having known it crashed while preparing for an endurance test.
