"The Loop" (9:30 p.m., Fox): Laughs are at a premium in "The Loop," a hyperactive new sitcom about a young airline executive (Bret Harrison) and his slacker friends. Sadly, the show too often fails to earn its wings. Mimi Rogers also stars.
"Babies: Special Delivery" (9 p.m., Discovery Health Channel): This special has featured hundreds of high-risk pregnancies and births during the past five seasons. Now it revisits five of its extraordinary deliveries to provide a timely update. The episode, "Growing Up," recaps the stressful moments of those births and picks up where the delivery room and maternity ward cameras left off. The youngsters include Nicholas, born with respiratory distress and put on a ventilator with little hope for survival.
