Looking good! Less spaceplane, more capsule. Pilot seat would be all-screen setup, with windows providing view for passengers. :D

?

Not seeing the "less spaceplane" part, cause—wings.

In terms of a traditional windscreen? Not like it matters that much.

It's probably subjective, but new model lines look to me as if they shifting away from wings to more lifting body profile.

It's exactly the opposite.

The current SNC DC is a lifting body (basically the HL-20).

The DC-200 is not a lifting body.

As a 2000s kid who grew up on outdated books from the 90s that still showed things like Hermes, HOPE, and the HL-20, it’s super cool to see a new civilian spaceplane come to fruition!

I have this reoccurring intrusive thought image of Dream Chaser on top a Falcon 9

Key takeaways:

Supply-chain issues due to the pandemic caused them to take production of a majority of the components in-house.

The biggest headache was creating the non-toxic thrusters to allow them to walk up to it on the runway. They run on kerosene and peroxide. Apparently, they're now the experts in working with both peroxide and zirconium, which doesn't decompose peroxide.

Building the second one will take about two years but cost half as much.

Seeing if they can recover the cargo module is also on their minds.

They're still in the design phase of the human-scale DC-200. The lack of fairing and the need for an abort system means they're trying to be creative.
