Also, the A300-600 ST (Super Transporter) or "Beluga" as they are known are used to ferry various Airbus parts around the European manufacturing and final assembly lines.

you can see it disgorging the fuselage and wings of a Vietnamese A350 at the Tolouse FAL.
They are getting a bit long in the tooth now so will shortly be replaced with some A330 ST
