R/C gliders that are built for manuevring performance often have T-tails while those built for maximum lift (for scavenging thermals) have a fortizonatl stab inline with the wings. The horizontal stab riding in the main wing's shadow creates less drag and thus probably is more fuel economical. >Also some more modern airliners have T-Tails, >(Bae-146 or Avrojet, MD-80/MD-90) ^^^^^^^^^^^ Descendant of a DC-9 so it probably would have been too expensive to redeisng considering the engines are iin the way. >, ATR 40, (I think thats >what this prop-plane is called), Fokker-100. ^^^^^^^^^^ Descendant of the F-28 >I find it difficult to distinguish at a glance an A330 >from a 767 / 777, a 737-400 from an A320, an A310 from a 757 ^^^^^^^^^^^^^^^^ Easy. the 757 is long and skinny and the engines almost look as big as the fuse! The A310 looks more like the A300s and A330s (same fuse cross-section) and a scaled up 737 >or TU-204. Will there ever be another T-Tailed airliner >after the current ones become obsolete ?

And let's not forget the Dassault Mercure that looked like a B-737 9don't think I've ever seen one).
