If I had to guess, it would be the following:
1) The IAF coverted the last of the straight pipe -321's only in recent years
2) The GE test bed -321 in Mojave got replaced by the 741 in recent years too
Both of the above were well into the 2000's. Not sure when the last of turbojet KC-135A models flew, but those would have to be considered.
As for short body -100's, I doubt any of those made it into the 90's but I am not sure..

What about the Omega Tanker 707's?
N707MQ is a 707-368C and N707AR is a 707-321B both which still use JT-3D's. They are a privately owned aircraft and not a military or government owned like most 707's flying today. They perform revenue flights, although they are hauling passengers.
I'm like a kid in a candy store when it comes to planes!

I think it was the IAF one. I remember a discussion on this website when a (then) current picture of it taking off appeared in the database... And almost immediately after that it was withdrawn and converted to turbofans.
I also remember actually hearing the old Vomit Comet taking off from PHX on its last flight down to Davis-Monthan/Pima museum, which was around 2001-2002...

No, these have turbofans. The OP asks for the early turbojet engined 707s, they were built mainly before 1961. The engine cowlings are smooth, unlike the later turbofans which have two sections. Also at the back of the engines there are about 15 'organ pipes' fitted for noise supression, but still these engines were even more noisy and smoky then the later ones.
Pan Am, TWA and Air France held on to sizeable fleets of these early 707s til the 1970s, while American and Qantas converted them to turbofans after 1961 and many other airlines only took the later models.

I'd love to hear a 707-320 take off from the cabin - the 321B/Cs have the distinctive "buzzsaw" sound on take off that most engines have today. I wonder if the turbojets did?
They were also relatively "weak" engines, at least they were by the time the turbofans came out. I don't think any Boeing aircraft were as underpowered as the original non-turbofan Boeing 720s.

Wasn't Mahan Air or other Iranian operator still flying 707s a very few years ago? I recall reading a trip report here in a.net (I think it was from Sam Chui).
Without knowing what powerplant they had, they did look like having turbojets.

Am I going crazy here...I've been to the Udvar-Hazy and I'd swear that 367-80 has turbofans on it now based on the look of the cowlings...they aren't smooth like I'm used to seeing for turbojets.

I think the winner of this contest might be N707GE as indicated by Crownvic above.
I recall having seen a picture on a.net of an Israeli 707-328 (or -321) turbo-jet taking off from Mallorca (?).
The pictures was, as I recall it, taken in 2007.
I was quite amazed when I saw it.
The picture does sadly not appear to be in the db anymore.

By then it was no longer a turbojet. The Dash-80 had been re-engined with JT3D turbofans in the 1960s.
Quoting 4holer (Reply 4): I think it was the IAF one. I remember a discussion on this website when a (then) current picture of it taking off appeared in the database... And almost immediately after that it was withdrawn and converted to turbofans.
Probably this ex-SN 707-329. It was still in IAF service as of 2006. Not sure if it still is. It still had the original JT4A turbojets until sometime between 2003 and 2006 when it first appeared with JT3Ds. As of 2006 I believe it was the oldest 707 still flying, 47 years after it was rolled out at Renton December 18, 1959. It must be one of very few early turbojet 707-320s re-engined with JT3Ds. I don't believe that modification was ever offered or certified for commercially-operated turbojet 707-320s.
There used to be an A.net photo in IAF livery dated around 2003 with the original JT4As but that photo seems to have been deleted from the database. You can still see the thumbnail of that photo in Reply 20 in the following 2007 thread (upper left photo) but it won't open when you click on it. What Is The Oldest Passenger Jet In Service?

Yes, this was the picture which was in the db.

Must have been that Orbis DC-8-21 N220RB which retired to a Chinese museum in 1994.

The JT-3D is a turbofan, the JT-3C is a turbojet.

A very loud ROAR......at take-off power the JT-3C, dry thrust was around 135 db, if it was using water injection it was even louder around 155 db.

I beleive the last commerical airliner I flew with turbo jets was in 1978 or 1979. It was a sub airplane for an L-1011, a B-707-131 with JT-3C engines (which are very close to the J-57 engines on my KC-135A/Qs. The flight was a TRANSCON, SFO-BOS. TWA was moving a few B-707-131s to the BOS base at the time (they flew the BOS-PIT-IND-ORD-BOS routing, usually), and when the L-1011 was not avaiable, and a light pax load (for the L-1011), the old -131 was flown on the route.
The picture does sadly not appear to be in the db anymore.

I was a crew chief on the KC-135A just as my ANG unit was switching to the KC-135E. Those E model engines looked HUGE compared to the old A model and now the R model engines of course make those original engines look like something you would see on a lear jet, not on a transport catagory aircraft. The worst job as a crew chief was cleaning the starters when the aircrew used the starter cartridges on a practice alert start.
I flew on an A Model a couple of times as a basic crew chief and had my first flight on an R Model in boom school at Altus AFB in '97. I couldnt get over how quiet the engines were on the R. There was no change in the sound of the airflow around the cockpit at cruise which was loud but the takeoff roll was fairly quiet. I still dont understand why the USAF paid extra money to have the thrust reversers removed from that engine!
