Servicemembers willing to undergo dangerous test pilot duties are remarkably brave. The military is now conducting tests on different body sizes to ensure women serving as pilots get the same safety benefits.

Via Airman magazine:

There are very few missions requiring years of planning and preparation, only to be accomplished in less than six seconds. There are even fewer facilities where such a mission can take place. The Holloman High-Speed Test Track, operated by the 846th Test Squadron, is one facility that enables test scientists and engineers to meet both of the above criteria. The test track is a 10-mile long, precision-aligned track that provides scientists and engineers a platform from which to conduct their various missions. Tests on the track provide valid data on problems which cannot be solved by other ground test means.
