It just occured to me that the CH-47 Chinook are still produced :-o
I would say that the remarkable Chinook have been there all time, and as it was introduced only 3 years after my birth it practically have, but it surprises me that the production is still active 55-years anniversary coming up next year.
The design have obviously not been superceded by anything in the meantime!

Had to share my surprise with You!

I believe the CH-47 is our heaviest-lift helicopter. It can lift just slightly more than the old Skycrane (S-62). Everything has been upgraded, and it has been produce along with the C-130 for almost the same amount of time. The C-130 has been in production 8 years longer or so, but both have been around almost since the earth cooled, relative to the production life of most aircraft.

 

One notable exception is the Beechcraft Bonanza that has been flitting about local skies since 1947 and is still in production.

Since the Bonanza became mentioned: Do You know how the engine have developed through that time?

I believe the Debonaire started out with 225 HP from a Continental engine of  470 cubic inches of displacement. In 1966 it got a 285 HP Lycoming O-520 six cylinder engine (520 cubic inches).

 

The model 35 Bonanza started out with a 165 HP E-185 engine in 1947. It went to 185 HP in 1951, and 260 HP in 1961. The S-35 went with an IO-520 and the V-35 has the TSIO-520.

 

In 1968 they stretched the V-35 to the model 36. It started with 285 HP and now has a 300 HP or 325 HP engine.

 

There are numerous turbine versions up to over 450 HP, including the military T-34 Mentor, whish has both piston and turbine versions. The turbine Mentors have both Allison 250 and PT-6A turboprops. The PT-6 versions in the T-34C has a 750 HP rating from an engine taht CAN produce over 1,600 HP in other versions. The T-34 uses it in a flat-rated condition.

The C-130 has been ... around almost since the earth cooled, ...

 

Well, maybe not quite that long, but, as recent research showed modern birds are closely-related to bipedal predatory dinosaurs, could there be a direct line of development between dinosaurs and the C-130? The following picture might show a necessary intermediate step (esp. the inclusion of motors and propellers into a biological concept):

BTW, this political dinosaur (according to his methods, not to his age) seems to need a special backhead care when placed into an aircraft:

(Of course, this MiG is not in flying condition, for the reason of weight excess.)

One more reason to assume that flying dinosaurs like the C-130 and the Bonanza derive from real dinosaurs! :)
