Capt. Jennifer Hailey always spent as much time as she could at her aunts house in the mountains. There she would camp by herself and explore for hours. The schools she was attending were boring for her, lacking in challenge. She enrolled at the Airforce Academy, finally finding her niche.

A 5''7' fighting machine, Hailey doesn't let anything get in her way when a job needs to be done. This attitude almost got her expelled from the academy when she thoroughly beat up a senior airman her freshman year. After she graduated, Hailey worked for 5 months on the LAPD, coordinating SWAT snatch-and-grabs for hostage situations. The following winter the US Airforce approached her, offering a position in a top secret government project. Always wanting to be where the action was, she agreed without hesitation.

Capt. Hailey secured her spot on SG-2 the hard way. Instead of taking the position because of her airforce academy training, she re-took the complete battery of mental and physical tests, beating 34 other candidates and firmly securing her spot on SG-2.
