How many were made? 394 and a half (the last one was scrapped while partially completed in the factory)
with approx. 300 in active service.
As a pax, have to say I sometimes love it and sometimes hate it. It's nice to fly on something a bit different and 'interesting' - hardly an annonymous metal tube by any stretch of the imagination. The odd fuselage width either means you get loads of room in a 2x3 configuration or are squashed in at 45 degrees to the wall when in 3x3.
I have one question - does the a/c suffer from a particular difficulty as regards weight and balance? Reason I ask is that I was once on a lightly loaded 146 flight where all the pax were moved from their assigned seats to the front half of the cabin before takeoff.
