Drop Tower

During the 1960’s North American Aviation, in their design of the Apollo Command module, constructed and used a 150ft tall drop tower, taking Apollo capsules up and dropping them into water to find a safe speed to land astronauts at. Now its your turn to design your own lander using parachutes and soft elements to safely land a crew from the top of a 25ft tall drop tower. Will an airbag system slow them down on impact, or will the air resitence of a parachute be necessary?
