Lynn Lunsford with the Federal Aviation Administration (FAA) said in a statement that the accident happened about 8.40am local time on Saturday near Lockhart, Texas, when the hot air balloon crashed into a pasture.
Ms Lunsford said that the FAA and the National Transportation Safety Board are going to the scene to investigate.
Lockhart is about 30 miles south of Austin.
National Transportation Safety Board spokesman Eric Weiss said that his agency's investigative team should arrive later on Saturday.
He said the safety agency knows "very, very little right now" about what happened.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
