The three-hour flight above south-west France used a modified Airbus A300 known as "Zero-G", which flies parabolic curves that give its passengers 20-second periods of weightlessness. | The three-hour flight above south-west France used a modified Airbus A300 known as "Zero-G", which flies parabolic curves that give its passengers 20-second periods of weightlessness. |
The patient was reportedly administered a local anaesthetic before take-off, at 0930 local time (0730 GMT). | |
French TV said that the operation took no more than 11 minutes, with 31 zero gravity sequences lasting 22 seconds each. The flight took just over three hours. | |
It is not yet known whether the operation was successful. | It is not yet known whether the operation was successful. |

"Since February we have been rehearsing this operation on the ground and in the plane. It is all crystal clear in our heads," said chief surgeon Dominique Martin, quoted by AFP news agency, before the flight began. | "Since February we have been rehearsing this operation on the ground and in the plane.

Surgical team member Professor Pierre Vaida, from Bordeaux Hospital, told the BBC: "The space station today is about 400km from the Earth, so it's very easy to have an astronaut come back in an emergency (to the) ground. | Surgical team member Professor Pierre Vaida, from Bordeaux Hospital, told the BBC: "The space station today is about 400km from the Earth, so it's very easy to have an astronaut come back in an emergency (to the) ground. |
"When we are out of Earth's gravitational attraction, it takes several days, at least, to come back. So it will be necessary to organise tele-medicine and tele-surgery to be able to take care of astronaut health." | "When we are out of Earth's gravitational attraction, it takes several days, at least, to come back.
