NTSB chair Jennifer Homendy said on Tuesday that an investigation into the cause of the Baltimore bridge collapse (after a container ship collided into it), and the resulting search and rescue operation, are ongoing. However, as for the number of fatalities or injuries, she said the NTSB cannot provide comment. Homendy also said the current priority of the NTSB are the loved ones of those involved in the incident that occurred early Tuesday morning.
