A hot air balloon has landed in a Massachusetts transit agency parking lot, damaging at least two parked cars.

Massachusetts Bay Transportation Authority police say the balloon was supposed to land in a nearby field in Grafton, but a strong wind gust knocked it off course Tuesday morning.

The balloon then made a hard landing in the MBTA lot.

Seven people were aboard the balloon, but fire officials say no one was injured.

An MBTA police spokesman says the incident is under investigation.
