Are there any JT-4a or JT-3c equipped planes still flying anywhere? Also any other first generation jets like Caravelle, Comet or maybe even some Tridents? I remember there was an Israeli 707 still with the turbojets photographed not too long ago. Anyone have any sound clips of these monster engines?

I think the last "diesel" was infact that 707 from Israeli Air Force. GE had also a 707-321 for a long time but that was scrapped too! I don't know if there are any DC-8 "diesels" still flying in Africa or South America. Caravelles there are 1 or 2 still in Africa but these are turbofan powered. Regarding BAC 1-11, maybe still a few in the executive world!

The BAC 1-11 has Speys, which are second-generation turbofans (Conways were first-generation).
The only civil aircraft with turbojets that I can think of that are still flying are the Sabreliners and JetStars with JT12As and Learjets, Hansa Jets, Jet Commanders and Westwinds with CJ610s.
Considering military aircraft, there are the A-3s that Raytheon operates (J57/JT3C), MiG-15s (VK-1), MiG-17s (VK-1), MiG-19s (RD-9), MiG-21s (R-13), T-37s (J69), F-4s (J79) T-2s (J85) and F-5s (J85) still in service.

Quoting Sovietjet (Reply 4): ll B-52s currently flying are powered by TF-33(JT-3D) turbofans. I was talking about B-52s like these:
The "diesel" B-52s are long gone as part of an agreement we have with Russia. The H models currently in service have turbofans, and they're the only 44 models still around. There is also plans in the work to replace the eight TF-33s with four modern *high bypass* turbofans of some sort so they can fly until 2040.

T-38s can be added to that list. The J85 isn't going anywhere anytime soon because it's one of the more efficient turbojets and there's nothing else in the (small) size class to replace it with. The USAF plans to keep the T-38s until 2040!
There are a number of military aircraft still flying with turbojets, but I believe the majority of civil aircraft are now turbofans.
