Rebecca Hastings was a Captain in the United States Air Force.
Captain Rebecca Hastings, USAF, was a fighter pilot who was grounded from flying following the discovery of a medical condition. She was one of the numerous candidates who applied for the vacancy caused by Ziva's return to Mossad. She was recommended to Gibbs by DiNozzo and McGee who had conducted the initial interview. Gibbs approved the choice and, after her interview, told her to report to Agents DiNozzo and McGee in the forensics lab.
Upon arriving at the lab she overheard DiNozzo, McGee and Abby discussing whether to hack into either Director Vance's computer or to hack into the Mossad computer systems in order to uncover information related to Ziva and her mission. Captain Hastings registered her disapproval and her unwillingness to participate in the enterprise. She walked out of the lab and was never seen or mentioned again.
