Why are the engine pylons different on this aircraft? Are all 707s like this? photo:

It's been reengined with JT8Ds. Only a few were reengined this way.

It looks like this airplane has been modifieid with either JT3D-7B's or JT8D-219. But the doghouse on tom of the pylon is a fairing for the turbocompressor.

NOT re-engined, still has the JT3D-3B engines, but IS fitted with the Burbank Aeronautical stage 3 hushkits. actively for sale...$3.5mil, last I heard.

A long ranger as well, 12 hours non-stop, at M.82, burning 12,000 pounds/hr. to start, reducing to 10,000 pounds/hr at hour six.

Nicely fitted out with three staterooms, I believe.

I wonder if John Travolta will ever hush kit his 707-138 with those types of kits
I would help you but it is not in the contract

If it is just the pylons, it was discussed here a couple of years ago.

Actually the pylons look very simliar if not the same to the ones that are on the standard 707. They still house turbocompressors above engines 2, 3 and 4. The engine is still a JT3D, but it's been hushkitted, looks very similar to what the DC-8 super 60s had. Good looking plane, saw it at Garrett at LAX the other day
