NTSB investigators seek clues after Pittsburgh bridge collapse
CNN
National Transportation Safety Board investigators descended into a wooded ravine in Pittsburgh Saturday where a snow-covered bridge collapsed one day earlier.
Investigators also flew a drone over the area in search of answers as to why the 52-year-old steel frame bridge collapsed in the predawn darkness Friday, leaving 10 people with what authorities said were non-life-threatening injuries.
The NTSB investigation will examine the full history of the bridge, including design, construction, and maintenance, NTSB chairwoman Jennifer Homendy said.

Secretary of Defense Pete Hegseth announced Monday that the Pentagon is taking administrative action to punish Sen. Mark Kelly, a retired Navy captain, by cutting his retirement pay for participating in a video where he and other Democratic lawmakers reminded US service members of their duty to refuse illegal orders.
