@farmerman,
Sorry, been a few busy days, I am trying to squeeze in when I can on my lunch break now.
This link explains in much more detail than space here permits.

Keep in mind this simple parallel when examining the evidence regarding the speed of radioactive decay:
As I have given an example of how evolutionists assume that flesh eating Has always been the normal because that is what we observe today, in the present.
Yet, because there is much evidence like vegetarian lions, vegetarian spiders, piranha, vultures, etc. etc.
It is reasonable to assume that it is possible that creatures we do not observe like mosquitoes for example were vegetarian as well in the distant past (which we cannot measure, just like radioactive decay in the past)
We know for a fact that many decay rates are not constant, and can be sped up....we may not have observed other types, but it is reasonable to assume they too can be altered.
Just like some animals we observe being vegetarian like lions, suggest that other lions we do not observe being vegetarian Can be altered!
The accuracy of half-lives is based on a number of tests, but no half-life is absolutely precise. Scientists did not wait around for 5,730 years to make sure that the carbon-14 half-life really is 5,730 years! The problems may escalate with larger half-lives, such as that of uranium-238 which has (supposedly) a half-life of 4.4 billion years.
Accelerated Radioactive Decay
We know for a fact that the decay rates of elements such as beryllium and rhenium are not constant. Also, the RATE team (Radioisotopes and the Age of the Earth) has provided startling evidence for a much higher decay rate of elements such as uranium.
For a visible uranium radiohalo to form, uranium must emit 500 million alpha particles[4]. At present rates, this would take about 100 million years. By deduction, every visible radiohalo must be at least 100 million years old. But here we run into a problem.
Polonium has a very short existence. Polonium-210 has a half-life of about 138 days; polonium-214 has one of 164 microseconds, and polonium-218 one of three minutes. Now the formation of parentless polonium radiohalos requires a large amount of polonium, otherwise the polonium present would all decay away too quickly and there would be no radiohalo. This large amount of polonium is equal to 100 million years worth of uranium decay.
So, uranium had to decay for 100 million years in order to create the required amount of polonium needed to make a parentless polonium radiohalo. And here’s the problem: after 100 million years, the polonium already produced would have decayed away before a radiohalo could be made! This means that uranium decay must have been much, much faster in order to produce the required amount of polonium all ‘at once’ before it quickly decays away.
Polonium radiohalos show that uranium decay must have been up to a billion times faster than today! And because many other dating methods are calibrated with the uranium method, they too would be inaccurate.
As for your plane example, that can be a good one to use when explaining the speed which we observe it moving. The point is we cannot measure how fast it was going an hour before that because we were not there. The idea is to find out the starting point of the plane five hours prior to that time we observed it, but we would have to assume that it has been moving at a constant rate.....What you were implying is that the pilot put it on cruise control
Sorry if this post seems a bit choppy, got to get back to work
