A very interesting photo here, from Douglas, of a "Short Eight" - but with nacelles unlike any production nacelles that were ever seen in other series -50 DC-8s. In fact, the Super -62/-63 had nacelles that were visibly different still, despite having all the bypass ducted along their entire length.

Anyone know what the history of these nacelles here was, and why they never went into wide use in the series -50s?

May the wind be always at your back . . . except during takeoff & landing.

All the references I can find say that aircraft was used as a testbed to develop the new engine nacelles for the -62/-63.

I would guess that since the -50 series wasn't being ordered in large numbers by then, there wasn't any point in spending a lot of money to certify new engine nacelles for the -50 series since they would only be ready for production about the time the last -50s were being delivered..
