Internal disagreements appear to be hampering the investigation into the Progress launch failure in late April.
The investigation had been leaning to pinning the failure on the disintegration of the Soyuz third stage oxygen tank. Others, however, are now claiming that the disintegration itself was caused by an improper separation of Progress from the rocket. The result is that the investigation has delayed the release of its findings.
