Gospel Mission Aviation (GMA) is one of the first officially recognized supporting ministries of the Seventh-Day Adventist church in Bolivia. GMA exists to be the hands of Jesus, bringing the gospel message to remote areas through missionary aviation.The mission plane serves in an air-medevac capacity and transports medical teams, pastors, and bible workers into these difficult to reach areas.

At the age of 7, while watching a mission aviation report, the thought of being a missionary pilot came to mind of Belgrove Josiah. This desire was forgotten for a number of years until many years later Belgrove grew a passion for aviation. Soon after this, the Lord rekindled the desire in his heart to become a missionary helicopter and airplane pilot.
