Wow, didn't realized that project was so advanced in its schedule. Looking at the photo I felt "this is no longer powerpoint or CGI. This is real."

Technically it's pretty far behind schedule.

And the drop test is a year behind schedule.

I thought they were doing OK schedule wise until they lost access to the White Knight. Of course, their ETA at the time probably wasn't really ready enough for those drop tests anyway.

it looks like their agreement with Lockheed has things moving along again.

True if you donít consider the loss of WK2 availability and CC not being funded at the requested levels...

They were making great progress until VG decided that the WK2 was needed to support SS2, and wasn't available for DC testing.

There were a bunch of milestones related to mating the DC to the WK2 and captive carry tests. Without help from VG, they needed to find a new partner.

They seem no more behind than either of the other CCiCaP competitors...

Great article Chris!  :) Nice to see the little bird begin to stretch her legs. What no Toyota?  ;D

The previous picture had the Skid strip on top of a dolly for towing.

I wonder if they are going to actually let the skid strip touch the runway for any of these tests, or if they are just testing that the assembly doesn't collapse during the test. How do you fully test the skid strip during these towing tests ?

Thanks for pointing out the towing dolly; when I first read about Dream Chaser's nose skid, I wondered how she was going to be towed, and now I know! :)

So that means that the entire (horizontal/pulling) load of the vehicle when towing is transferred through the skid... interesting!

Question for Chris or whoever might know.  The article says
Quote
Dream Chaser – also known unofficially as “Eagle” – will also end her mission by landing on a runway, although there will be some key differences, especially during the actual touchdown.

What are those differences? If you mean between DC and shuttle I'm clear... but it almost read like there are key differences between "Eagle" and the launchable version. Thanks!

I hope this will be a routine image after a several thousand kilometer trip :)
Super article Chris.

Looks like they are using two different tow dollies from the photos (low and high speed). One of them may have a quick release for detachment at high speed in the last pic from the skid.

maybe - there appears to be three wheels up front and possibly an attachment to the DC body itself (blow up the picture) so maybe we need a better sideways shot??

I think thatís an angle illusion caused by the right rear main gear. I see only two on the dolly... Let's chip in and send Lee Jay there for a photo... ;D

Your probably right on the "third wheel" and ...how much will Lee Jay need?
