Engineers at NASA’s Langley Research Center in Hampton, Va., dropped an old Marine CH-46E helicopter fuselage filled with 15 dummy occupants from a height of about 30 ft to test improved seats and seatbelts and gather data on the odds of surviving a helicopter crash. They used cables to hoist the helicopter fuselage with its mock passengers into the air and swing it to the ground, much like a pendulum.

Schuler Group, Canton, Mich., offers a heat-treating technology called press-hardening to increase the strength of steel parts. In this technology, blanks or pre-formed parts are heated in a furnace to a temperature of 930°C, then placed into the press as quickly as possible, within just 10-12 seconds. The press remains closed for a few additional seconds during the forming process. During this time, the parts are cooled and hardened. The cycle times range from 8 to 30 seconds.
