Surveillance drones operated on the U.S.-Mexican border cost between $2,500 and$3,500 per flight hour. Each drone requires an hour of maintenance for every hour it spends in the air. Each Predator and Reaper drone (our most common strike drones) requires a team of 180 people to operate. properly. The cost of producing a military drone ranges from $100,000 to hundreds of millions of dollars. Over the next decade, the Pentagon plans to spend $40 billion on medium-to-large sized drones.
Most infants born at 36 and 37 weeks' gestation are mature enough to be discharged from the hospital with the mother. But many premature infants need care in the neonatal intensive care unit (NICU). Hospital care will be needed for: 1  Underdeveloped lungs. 2  Inability to breathe continuously (apnea of prematurity) . 3  Inability to maintain body heat.
A baby born before 33 weeks will have more serious problems such as immature lungs. Very premature babies (born under 28 weeks) need to be delivered in a hospital with a neonatal intensive care unit. Doctors have been able to improve dramatically the survival hopes for babies born as early as 22 or 23 weeks. However, very premature babies face a huge battle at the start of life.
