80 years for a technology. Wow

I saw a working DC-3 flying recently probably more than 60 years old
and first ones developed and built in the 1930's even more amazing
considering the how relatively close to dawn of flight that was.

How many other high technologies are still in active service at that age?

Some of the original old beam pump engines that were used for pumping water
out of mines, and for supplying city water here in the UK, would match that.

But what I think is the amazing part of the B52 life time, is that it is
PLANNED as being in service as a design for a full century. OK that may well
not have been the plan when originally designed, but it is the current plan,
because the costs of developing a replacement is so huge, and they are so
d***ed good at the job they do.

Massachusetts had a small fleet of DC3s at least a few years ago.  I
remember them mentioning that on the radio once when discussing spraying
against mosquitos that were causing eastern equine encephalitis.

Plenty, but I guess it depends on what you call "high technology".  Being
able to produce fire on demand must have been pretty high tech and way cool
30000 years ago.  Steam engines and their modern derivatives were the
leading edge of technology not that long ago, and modern engines are still
at the leading edge of technology.  This list goes on.  AM radio, broadcast
television, color television (now that was a really clever and high tech
enhancement to B+W television in my opinion), automobiles, the transistor.
Some of these are a bit newer than powered flight, but are also expected to
be around for a while.

I wonder how much of the original plane will be actually flying at the end
of that time. Will they end up being like Trigger's broom? Only Fools &
Horses anyone?<http://www.bbc.co.uk/comedy/onlyfools/quotes/quote11.shtml>

The DC3 will be around for quite a while yet.  Here is a company about
20 minutes from me that is converting them and they have "0" hours on
them when they come out the door.  I have rode in one ant even have 30
minutes copilot time in one.  Fantastic airplane.

it's more a case of the family axe; three handles and two heads  and its
still working! simple technology is usually easy to fix and tougher.

I think the "family axe" example is not correct here.  A lot of the main
frame components are still original components.

One reason for the long life is spares supply,how many are sat out in the
desert 'waiting' to be put back to service at short notice? or am i out of
touch, the last time I went to an airshow i stood in front of a Hawker sea
Fury as it revved up,probably wouldn't be allowed now
due to noise levels, never mind safety!
(i was only about fifteen feet from it!)Ah the good old days..pass me my
pipe and slippers...zzzz
