The first in a series of charter flights will leave JFK International Airport for Haiti Saturday, carrying nearly 50 medical doctors from the Association of Haitian Physicians Abroad.

The flight -- organized by the Church of Scientology -- will provide urgently needed care in the wake of Tuesday's 7.0 magnitude quake.

Teams of Scientology Volunteer Ministers from the U.S., Mexico and Europe will aid in search and rescue efforts, provide administrative and organizational support, and support medical teams.

The church will also provide large, yellow tents to be used as field hospitals, and trauma relief and counseling centers.

The Scientology Volunteer Ministers Corps -- incorporating 230,000 Volunteer Ministers worldwide -- aims to provide community service, disaster relief and emergency response. They've served at some of the world's worst disaster sites, including Ground Zero, the Southeast Asia tsunami and Hurricane Katrina.
