Regarding the "fly-by-wire" question, this is from Airbus Industrie's own website:
The A300/A310 Family have been outstanding pioneers in such valuable innovative technological features as fuel-reducing wingtip devices, identical CRT displays on the flight deck, automatic windshear protection and digital electrical signalling (fly-by-wire) for slats, flaps and spoilers - reducing workload, maintenance and saving weight. Both aircraft are certificated for up to 180-minutes ETOPS operations, with both General Electric CF6-80 or Pratt & Whitney PW4000 engines.
So, the A300 is fly-by-wire for some controls, but not for the basic aileron, elevator and rudder
