The Massachusetts man was given a ride in a hot air balloon for his birthday.
The 63-year-old Avery ended up with two broken legs and two broken ankles.
A half hour after lift off, the wind came up forcing a hard landing in Sandown, New Hampshire.
The gift was from Avery's daughter.
He'll now miss six weeks of work.
But Avery says once he's healed, he'd try another balloon ride.
