Off the top of my head:
1. "Every year we hear about people dying in plane crashes. This does not have to continue..." But air travel is already the safest mode of travel. Hear all those people screaming for new technology to make road travel safe? No? Well, they're the same ones that will take this up.
2. "Passengers might board a capsule at a local bus station and wake up in another city on the other side of the country, or planet, after a road, air and rail journey during which they didn't leave their seat." They don't seem to realise the blindingly obvious point that this is making air travel *worse*. Air travel already involves sitting in a seat for too long. Why would I opt for a mode of travel that exchanges a few minutes of having to be polite to people in the aisles for one that involves several hours more in the same damn seat?
3. If you want to see just how off-their-faces unrealistic this is, look no further than this sentence: "Clip-Air's researchers, who are also looking into the possibility of using biofuels or liquid hydrogen as alternative fuels, have already initiated some contacts with the aerospace industry." Oh, great! You're launching publicity for a total redesign of the entire global air freight and passenger industry and you've *already* initiated some contacts with the aerospace industry??? Really??? What made you do that so soon??? And looking into hydrogen as a fuel source for this is basically admitting, "It's so far off the page that we might as well throw in any futuristic-sounding crap we can." If you're doing this seriously, get one thing right at a time. Don't complicate it by also trying to introduce a fuel that no-one else has managed to make work yet.
People who consider themselves "aviation visionaries" (yes, an actual term used in the article) always, always get excited about this kind of thing for no good reason. They *think* people want revolutionary concepts that change how they board planes and let them work out then drink themselves silly in a trendy bar while they're in flight. What people *actually* want are revolutionary new concepts that cut the cost of air travel.
