Some interesting comments from chief of piloted programs Alexei Krasnov via ITAR-TASS:
"The malfunction was found in the service elements of the descent capsule....but no decision was taken to delay a forthcoming launch.
Krasnov acknowledged that several days ago some problems really emerged....but the problems are related to a service element, rather than the descent capsule,
Krasnov did not rule out that “the schedule of piloted missions will be revised,” but he sees no tragedy in this. “There are program reserves to deal with the emerged problem,” he underlined.
“It is very good that upon the results of the tests we received critical remarks before the spaceship was brought to the Baikonur spaceport, because we have some time and possibilities to examine everything in detail,” Krasnov concluded.
