Nicole Kirkwood, a Detroit Police spokeswoman, tells the Detroit Free Press early reports suggest the plane had to land Monday night because it was running out of fuel.
The plane went down in the middle of a residential street, injuring the pilot. On its descent, Kirkwood says the plane struck a live power line that fell, hitting a passer-by. She says that person was taken to a hospital in serious condition.
The Detroit News, citing city spokesman John Roach, reports the plane had been trailing a banner over crowds gathered for an annual fireworks display over the Detroit River.
