Meh, I let my Popular Science subscription go when I was a teenager. Kitplanes? We'll see.They pays for the ad-space, they gets to run what they want, provided it doesn't break the (usually "no nudity, no drugs, nothing we can't show our moms") publication's advertising rules.
The only thing keeping this from being a full spread ad is that it would cost about 3-4 times as much.
I don't see any significant gaps in their experience. If they had an aeronautical engineer, or a structural engineer, or even a pilot on the team, well, such people are full of old thinking constrained by old paradigms. They crush innovative new ideas
