I can show you a lot of pics with ppl rope-walking on their hands. That don't make the such ideas more sane and safe. Using parachuteless landing for manned flights, are same crazy as jumping from waterfall in the barrel. There is no thrusted landing system with same statistic of success as parachute landing and will not appear in this century. Even a such simple system as Soyuz' DMPs making mistakes.

To pm1823:
And why we do not have such statistics?

BTW Soyuz DMP system does not have anything with parashute (DMP or Engines for Soft Landing  are responsible for the decceleration on the last meter of descent).
 
There was only 1 incident recorded involved DMP failure - landing of Soyuz 35 on Jun 3, 1980 (crew: Farkas, Kubasov, and it was not a catastrophic event).

For your information, there is a SIGNIFICANT difference between Souyz landing module (2,8 metric tonn) and proposed vehicle landing module (~12 tonnes). Size does matter and in this scenario parashute system might be not scaled well.

Do not worry - this is still  a concept, not a real spacecraft.

Don't ever become a pessimist... a pessimist is correct oftener than an optimist, but an optimist has more fun, and neither can stop the march of events. - Robert Heinlein
