Soyuz capsule hatch nearly burned up during reentry

Finger pointing and spin including that "women on board space missions were bad luck". [Link]

Today, even more revelations have been reported. According to an unnamed Russian space official, the capsule had entered the atmosphere in an uncontrolled manner. Rather than the capsule's heat shield taking the frictional re-entry burn, the escape hatch became exposed and bore the brunt of the high temperatures outside. The hatch sustained substantial damage. The antenna was also exposed to the heat, completely burning it up, explaining why the crew were unable to communicate with the ground. A valve that equalizes cabin with atmospheric pressure was also damaged.

"The fact that the entire crew ended up whole and undamaged is a great success. Everything could have turned out much worse. You could say the situation was on a razor's edge." - Anonymous Russian space official involved in the descent investigation.

They're very lucky to be alive.
