Episode 9.6: Back In the Saddle
Airdate: Fall 2003

09/01 - Harm is on a Harley Davidson speeding on a highway and heading to Blackburg Municipal Airport where his Stearman is. To his surprise, a few other Stearmans are in the hanger as well as a new sign... "Grace Aviation". Harm asks a few questions to a teenage girl named Mattie Grace. He learns that the previous owner sold the hanger. She offers her help to Harm in repairing the plane. Mattie offers Harm a job as a pilot. At JAG HQ, Turner is in his office (which used to be Harm's office) reviewing paperwork as Mac comes in and says that they'll go to courtmartial. Seems that both are working opposite sides on the same case. Roberts also appear in the episode. Source: Izzy
