Retracting landing gear (China)?
So I'm standing with a bunch of other non-pilot plane-spotters watching AC depart runway 18L at ZSSS (Hongqiao Shanghai). A local carrier Airbus A330-200 takes off normally and disappears into cloud a little while later... with its landing gear still down! Question for professsional types; don't you want to retract the landing gear ASAP after clearing the runway? On this day Aviation Weather said broken cloud 2600 feet, ceiling 2600 feet. PS Actually I was the only plane spotter, the other folk were concentrating on catching fish in the canal.
