Two people were injured in a boat explosion at a New Jersey marina Wednesday afternoon. Old Bridge Township Police said officers were sent to the Raritan Marina just before 3:30 p.m. Video from Chopper 2 shows firefighters spraying water on a boat engulfed in flames in the creek. The flames sent plumes of black smoke billowing into the air. According to police, the explosion caused a 57-year-old man to be launched into the water. Police said he was rescued by bystanders and airlifted to a local hospital to be treated for burns to his face and legs. Police said a 47-year-old man was hit by glass and suffered injuries to his stomach and arms. He was taken to a local medical center for treatment. The cause of the explosion is still being investigated, but police said it does not appear to be suspicious.
