NASA Drop Test Supports Safer Air Taxi Designs

NASA Image of the Day - Tue, 07/29/2025 - 11:37am
An aircraft body modeled after an air taxi with weighted test dummies inside is being prepared for a drop test by researchers at NASA’s Langley Research Center in Hampton, Virginia. The test was completed June 26 at Langley’s Landing and Impact Research Facility. The aircraft was dropped from a tall steel structure, known as a gantry, after being hoisted about 35 feet in the air by cables. NASA researchers are investigating aircraft materials that best absorb impact forces in a crash.
