Around 4:30 p.m., people across the Financial District heard a loud boom. Those who happened to be on Federal Street in front of the Bank of America building, saw flames coming out of the rear tire well of an MBTA bus, followed quickly by the arrival of Boston firefighters, who doused the engine.
After they were done, T inspectors tried to figure out what had happened before the bus was towed away.
