In 1979, Living Water Teaching (LWT) came into being in the country of Guatemala, planted by Pastor Jim and Marion Zirkle. The ministry grew to include outreaches in eleven countries in Latin America. Bible schools, evangelistic campaigns, medical clinics, Operation Shoe-box. The ministry of LWT was reaching the nations for Christ.
Mercy Wings International was launched to complement the mission of LWT in Guatemala and surrounding countries. Aircraft would prove to be a valuable asset, on which the ministry mission could move forward. The fleet would grow to include: single, multi-engine, piston, and turbo-prop aircraft. In November 1998, a tragic accident would cause Mercy Wings to lay dormant for the next 10 years.
The many aircraft that once served LWT and the people of Guatemala have long since been placed into service elsewhere, save one, the last to join the Mercy Wings team, N2379F, a Cessna T206H.
In 2008, the revived Mercy Wings International (MWI) returned to Guatemala ready for flight and providing air services to further the mission of LWT by speeding humanitarian relief, supply, and the Gospel of Jesus Christ to the people of Latin America.
