We may never know what caused the 22 highway, aviation, marine and railway accidents that occurred during the partial government shutdown and were not investigated, because furloughed National Transportation Safety Board (NTSB) investigators did not physically visit the accidents sites. That, says the NTSB, means “that perishable evidence may have been lost, which potentially could prevent determination of probable cause.”

Like other government agencies affected by the shutdown, the NTSB resumed normal operations on Monday and took stock of how it had been impacted by the work stoppage.

Of the 397 agency staff, 367 employees were furloughed, 26 employees were excepted, and four investigators were recalled and worked without pay to support investigations of three international aviation accidents.

The numbers
