One A310 airframe was converted into a scientific research laboratory dedicated to weightlessness. The aircraft flies parabolas that provide twenty-two seconds of weightlessness per manoeuvre, the standard procedure of reduced-gravity aircraft for experimenting with free fall without leaving the atmosphere.
Who operates it
The A310 Zero G is operated by Novespace, a subsidiary of CNES — the French space agency — and is based at Bordeaux-Mérignac airport. Besides scientific flights it performs recreational flights under the Air Zero G brand and movie special effects work, such as for The Mummy (2017).
