Two people suffered minor injuries and a third person walked away after a hot air balloon went down at the Lockheed Martin space systems assembly plant in Littleton on Wednesday.
Lockheed spokesman Matt Kramer says the tour balloon came down in the parking lot of executive office buildings at the plant. The facility is used to assemble commercial and defense department space vehicles and satellites.
Mark Stokes of Littleton Fire Rescue says the balloon took off from a nearby park and landed hard when the wind shifted.
Stokes says the two people who were injured were taken to a hospital for treatment.
