Here are some Maryland State Police action & apparatus photos. You can learn more about MSP aviation here: www.mspaviation.org. The Maryland State Police changed the face of Emergency Medical Services in this country when they completed the first civilian Medevac in the country in 1970, and since then they have transported more than 100,000 patients. MSP Aviation Command today flies 12 Dauphin helicopters, known as "Troopers".
