Gisele Bündchen may be 6 months pregnant, but that’s not stopping her from taking lessons to learn to fly a helicopter, a friend confirms to PEOPLE.

While husband Tom Brady, 32, is in training with the New England Patriots, Bündchen has been doing her own training outside her new hometown of Boston. “She’s been coming to the airfield for a couple months and she started her lessons a few weeks ago,” says Keith Douglass, president of Shoreline Aviation, a company that provides private jets and aviation lessons.

“She’s gung ho about learning to fly. She’s one of the best students we’ve ever had,” says Douglass. “She’s excellent at learning and understanding what makes the helicopters fly. She knows all the rules and regulations. She’s fantastic at flying the helicopter. She is very smooth and professional and she listens.”
