After I have been in Bordeaux several times for scientific flights in the last years (see Partial-G flight und MIRIAM-2) and learned there that Novespace, under the name "Air Zero G" offers public flights since 2013 (so-called Discovery Flights) of course I couldn't resist. Especially, since the A310 of Novespace offers much more space than the Boeing 727 of Zero-G Corp.
Update coming soon! September 2022 Update coming soon!
One thing is clear: I hope there will be a next time!
I booked here: Dovespace (german bookings only). But all non-german speakers can book directly at Air Zero-G.
