On October 24, 2014, Dr. Alan Eustace used a state-of-the-art Pressure Suit Assembly to ascend to the top of the stratosphere beneath a large plastic balloon and sky dive back to Earth. He reportedly reached a maximum altitude of 135,889 feet.

This crash helmet was worn under the bubble helmet. It protected Alan Eustace from head trauma in the occurrence of an uncontrolled landing. The dual helmet regulators controlled the pressure in the helmet region of the suit and provided demand-regulated breathing oxygen are mounted to the helmet ring in the pressure suit. It has support pads near the ears.

The Eustace-Kwan family donated this item along with the suit to the Museum in 2015.
