On Tuesday night, a Defense Department training exercise gone wrong resulted in a Delta Air Lines pilot being mistakenly detained and interrogated in a Boston hotel. The FBI said personnel were sent to the wrong room during the exercise, and the Office of the Secretary of Defense said the "DoD routinely conducts training exercises with law enforcement agencies." The incident serves as a reminder of the importance of accuracy and attention to detail during training exercises, and it is unclear if any changes will be made to the training protocols.
