Our own Anatoly Zak has some new information about this on his
Russianspaceweb site.

No American space farer did this.  It was found by RKK Energia engineers
that a half-meter-long space drill would be needed to drill the hole at the
required angle..

 

 

Russian officials back "production defect" theory in the Soyuz accident

On September 11, Sergei Saveliev, Deputy Director General at Roskosmos,
announced that the State Corporation would inform all its partners on the
results of the investigation into the Soyuz leak and would seek other
agencies' endorsement of the Russian conclusions.

The next day, Deputy Prime Minister Yuri Borisov, who was appointed
<http://www.russianspaceweb.com/centers_industry_2010s.html#borisov>  in May
to oversee the rocket industry
<http://www.russianspaceweb.com/centers_industry.html> , said that it would
be absolutely unacceptable to drop even a shadow of an accusation either on
cosmonauts or astronauts while the investigation was in progress. "It is not
excluded that the culprit is in a production defect (and) many theories can
be drawn up," Borisov was quoted as saying by the official Russian media,
"The fact remains, the pressure began falling after several months of the
ship's presence in orbit. The hole is very small, it is good that it was
noticed in time and taken care of."

According to Borisov, the ISS crew is a united collective where there are no
political disagreements. "Today, before the conclusion of the investigation,
hanging labels and doing a witch hunt is, mildly speaking, shortsighted and
dangerous," Borisov said.

Borisov's statement also coincided with the report that early simulations
performed on the ground by investigators at the spacecraft manufacturer, RKK
Energia, showed a need for a half-a-meter-long drill in order to make a hole
inside the cramped compartment under the required angle. However, the same
hole could be easily made inside the unfurnished Habitation Module

industry sources said quoted by RIA Novosti.
