Observation on the drawings - on#20 the "front view" is actually the "Rear view", and the occupants/astronauts are facing backwards

Many Thanks BrightLight, I miss such information.

BTW I have a question: I suppose that pilot and co-pilot are facing through the windows while the other ones are facing backwards, is it correct?

I think you completely misunderstood what he meant.

He just said one of your your picture has a wrong title.

in my opinion, you are wrong.

in picture n. 20, the Dream Chaser, by my point of view, is cutted between the second and the third row of seats, and then viewed front side.

So, let me made up my mind.

Corgius has taken my point, Slide 20 view is correct.

I cut (ideally, of course) the DC looking backward (from front to back, I mean) so the view is correct (by drawing point of view).

As I see it, the image says "Front View" but the view is of the rear of the DC, further the occupants are facing the rear of DC, but the other views show the occupants facing forward, towards the front of the vehicle.
Regardless, your work is excellent.

Here it is.

Very cool but the seats on both the HL-20 and DreamChaser are spaced further apart to create a very narrow aisle between the two groups to allow the crew to exit through the rear of the craft.

Point of clarity - is this a HL-20 mock-up or a Dream Chaser mock-up.

Both. It was originally built around 1990 as the HL-20 mock-up. In June 2006, NASA Langley removed it from storage, resembled it and shipped it to Space Dev (which is now owned by Sierra Nevada). There it was used as the Dream Chaser mock-up. The picture I posted above was taken in July 2006 and so was this one.

Wrong, the HL-20 was displayed at the Virginia Air and Space Museum fully assembled, it was not in storage or in pieces. I witnessed it there quite often. The Virginia Air and Space Museum is also the Visitor's center for LaRC.

Very cool.  Just curious for people's opinion, but what are the chances that Dream Chaser actually makes it to crewed flights?

Various sources have stated that there will likely only one provider chosen to deliver crew and erioladastra has stated that Dream Chaser is behind Beoing and SpaceX.

Having a single provider would defeat the biggest advantage of commercial crew which is redundancy.

It should be noted Dream Chaser's method of decent and landing is well tested the same cannot be said for Spacex's chosen method for the crewed version of their vehicle.

I'm not defending the downselect or criticizing the Dream Chaser design. Anyway this isn't the best topic to discuss this.
