I recorded this back in 2009. Amerijet 213 working Oakland Center on 134.15 setting up the Zero-G parabolas off-shore San Francisco, CA

Affectionately knowen as "Vomit Comets"...  shocked

The aircraft Amerijet uses for this operation is Boeing 727-227/Adv(F) N794AJ (cn 21243/1197), pictured below.
The aircraft Novespace uses for this operation is Airbus A300B2-103 F-BUAD (cn 003) also below.
Below them, is a picture of the "cabin" on F-BUAD, soft mats line the floor, walls, and ceiling in the aft area, while upfront, seats for take-off and landing portions resemble stock airline issue seats, cabin slightly modified... wink

During flight tests, that maneuver is known as a symetrical pushover. Main reason is to check compliance with FAR regarding pitch stability and control, as well as structural integrity.
On a personal note, did that once while inputing a maximum nose down hardover from the autopilot at the zero-G point. Not recommended! Quite the negative G-load! Nothing bent or broke, but a quick way to lose your breakfast, as most of the aircrew did, including myself.
The opposite maneuver was the symetrical pull-up. Always a good positive G-load there during the pull-up.
