In an op-ed in IEEE Spectrum, James Oberg mentioned the statements coming from each organizations harken to a time when security tradition slipped at NASA in favor of political issues. “Whereas the proximate explanation for the incident continues to be being unravelled, there are worrisome indicators that NASA could also be repeating a number of the lapses that led to the lack of the Challenger and Columbia space shuttles and their crews,” he wrote. “And since political pressures appear to be driving a lot of the issue, solely an unbiased investigation with severe political heft can reverse any erosion in security tradition.”
An earlier model of this story mentioned the station rolled, indicating a single axis maneuver, nevertheless it really tumbled on all three axes.
