The National Transportation Safety Board (NTSB) is "stretched to the limit", says a study published by independent consultancy Rand.

Rand was referring particularly to a shortage of personnel. NTSB chairman Jim Hall has accused the US Office of Management and Budget of risking "the safety of the American people" by ignoring repeated requests for more investigative personnel.

The report suggests, however, that the agency is "insular" in its failure to use the expertise in other agencies and universities.
