SpaceX Tries Out Its New SuperDraco Rocket Engine

No, berthing is to be standard operating procedure for cargo flights; Common Berthing Mechanism [wikipedia.org] connectors, such as the one found on the nose of the Dragon, don't have any of the shock absorbers required for docking. As it also requires the Canada arm to unberth, CBM isn't well suited for manned flights, as in an evacuation scenario, there'd be no one left on the station to operate the arm, so crewed version of the Dragon will probably feature either APAS [wikipedia.org] or NDS/LIDS [wikipedia.org] docking connectors. CBM is preferred for cargo transfer, however, because it has a larger hatch, big enough to move fully assembled equipment racks through them. Japan's HTV cargo vehicles are also berthed via Canada Arm.
