 The _measured_ average drift of the four clocks was 8e-13.
But the drift of each clock was higher, so the precision
of the clocks was in the order 1e-12, or better.
 But during 65 hours the uncertainty would be ±235 ns
so it would obviously be impossible to measure anything
with such a clock without some kind of calibration.
 And of course Hafele and Keating knew that, they were not stupid
even if you think they were.
 This was what they did:
Before the Eastward trip, they compared the clocks to the standard clock
at the US Naval Observatory (USNO) for 240 hours, and noted their drift.
They did the same for 150 hours between the trips, and again for 110
hours after the Westward trip.
This way they could interpolate the drift during the trips.

See fig.1 and fig.3 and READ the text!
 When you criticise an experiment without having read the paper _carefully_ you will only make a fool of yourself!

Have you no comment to Hafele and Keating's paper?
Have you still not read it?

Is the Hafele-keating experiment credible?

And what was the answer? :-D

A quote from Bill Howel's blog:
"In the conventional interpretation, it is believed that Hafele and Keating proved that the east-bound clock slowed down by 59 nanoseconds and that the west-bound clock sped up by 273 nanoseconds relative to a clock in Washington. Even if true, this would be quite a shock. Einstein claimed that all moving clocks are supposed to run slow with respect to the observer. There should have been little difference between eastward and westward travel."
No clue! :-D
Another quote:
"In the second interpretation, skeptics have considered the experiment to have been a total failure due to the erratic behavior of the clocks (e.g., Spencer and Shama, 1996; Kelly, 2000)."
Quote from Kelly's paper:
See fig 1 in:
https://paulba.no/paper/Hafele_Keating.pdf
"Drifts determined when the clocks were on the ground in Washington were extrapolated across the time the clocks were in transit. Clock 408 was about the worst: it lost time (L) before the eastward flight and gained time (G) after the flight (Fig. 1). Clock 447 had the most consistent drift rate, but it showed no significant gain or loss during both flights (Fig. 1). On top of all this, Hafele and Keating had the temerity to average this mess (bold dashed line in the center of Fig. 1)"
It's not clear why Kelly found this to be "a mess".
Kelly is a well known crank.
I have read several of his papers.
They are all quite naive.

  There are plenty of critics available on the web. I only took the first
two links in the first page.

Of course there are.
Like there are plenty of critics of "the 9/11 was made by Al-Qaeda" theory.
