The pilot reported the ground winds were 1 to 2 miles per hour, and the winds between 500 and 1,500 feet above the ground varied from 5 to 8 miles per hour during the uneventful flight. He reported he chose a backyard in which to land, and at an altitude of seven to nine feet above the ground they threw a line out to the chase crew to slow them down. The pilot reported that before reaching the ground, two more chase crewmembers grabbed the gondola to slow them down even more and to soften the landing. Upon touching down, one passenger lost her balance and fell into a 91 year old passenger, knocking her to the bottom of the gondola. The 91 year old passenger suffered two broken legs and a broken ankle. The pilot reported that prior to the departure, all of the passengers were instructed to hold on tight, bend their knees, and stay inside the gondola during the landing.
