1. A conveyor apparatus for loading and unloading aircraft, said apparatus comprising: a first conveyor for conveying articles from an area outside of an aircraft to an entrance to a cargo compartment of the aircraft;a second conveyor comprising a plurality of conveyor segments for conveying articles from an end of said first conveyor into the cargo compartment, said second conveyor having a tail end adjacent said first conveyor and a head end at a distal end of said second conveyor;wherein said second conveyor is telescopically extendable from said first conveyor;a plurality of couplers joining adjacent ones of said plurality of conveyor segments, wherein said plurality of couplers permit pivoting movement between said adjacent ones of said conveyor segments;an endless flexible member extending along said plurality of conveyor segments between said tail end of said second conveyor and said head end of said second conveyor, said endless member comprising at least one chosen from (i) a drive chain, (ii) a belt, and (iii) a band extending between sprockets or pulleys mounted on respective ones of said head and tail ends of said second conveyor, wherein said endless member extends along a central axis of said second conveyor coincident with said couplers; anda driver configured to drive said endless member to convey articles along said second conveyor;wherein each of said conveyor segments includes a driven member engaging said endless member and at least one roller or wheel configured to be rotatably driven by said driven member for rotation about an axis extending transverse to said second conveyor, for conveying articles along said second conveyor. 2. A conveyor as claimed in claim 1, wherein said driver is provided on at least one end of said second conveyor. 3. A conveyor as claimed in claim 2, wherein said driver is provided at at least said head end of said second conveyor. 4. A conveyor as claimed in claim 1, wherein said driver comprises a first driver provided on said head end of said second conveyor for driving said second conveyor in a first direction, and wherein a second driver is provided at said tail end of said second conveyor for driving said second conveyer in a second direction, opposite said first direction. 5. A conveyor as claimed in claim 1, further comprising a guide on each of said conveyor segments of said second conveyor, wherein said guides are configured for guiding the path of said endless member. 6. A conveyor as claimed in claim 1, wherein each conveyor segment is provided with at least one ground engaging support wheel or roller on a lower side thereof. 7. A conveyor apparatus as claimed in claim 1, wherein said driven member comprises a sprocket. 8. A conveyor as claimed in claim 1, further comprising a plurality of conveyor flights mounted on said endless member and configured to be moved along said conveyor segments, each of said conveyor flights comprising a central portion coupled to said endless member and pair of opposing side wings extending transversely from said endless member to define a respective portion of a conveying surface. 9. A conveyor as claimed in claim 8, wherein said side wings taper from said central portion to a respective distal end thereof to permit mutual sideways pivotal movement of said conveyor segments. 10. A conveyor apparatus for loading and unloading aircraft, said apparatus comprising: a first conveyor for conveying articles from an area outside of an aircraft to an entrance to a cargo compartment of the aircraft;a second conveyor comprising a plurality of conveyor segments for conveying articles from an end of said first conveyor into said cargo compartment;wherein said second conveyor is telescopically extendable from said first conveyor;a plurality of couplers joining adjacent ones of said plurality of conveyor segments, wherein said couplers are configured to permit mutual sideways pivotal movement of adjacent ones of said conveyor segments to thereby provide an adjustable conveyor path;a single endless member mounted at said second conveyor and configured to convey articles therealong, wherein said endless member extends along a central axis of said second conveyor coincident with said couplers;a driven member at each of said conveyor segments, said driven member engaging said endless member; andat least one roller or wheel configured to be rotatably driven by said driven member for rotation about an axis extending transverse to said central axis of said second conveyor. 11. A conveyor apparatus as claimed in claim 10, wherein said endless member comprises an endless belt or chain. 12. A conveyor apparatus as claimed in claim 11, wherein a plurality of conveyor flights are mounted on said endless belt or chain to define a conveying surface.
