Even his former supporter writer Jeffery Kooistra has now publicly withdrawn support from van Flandern's ideas after the debates recorded in the URLs above, in a two-part essay discussing the debates in his 2001-Sep and 2001-Nov columns in _Analog_. (However, that hasn't stopped van Flandern and his fans from continuing to spew their discredited nonsense on the net.)

This article states at page 2:
"This result proves the claim above that the electric field from a uniform moving source is not aberated. The force on a test charge is directed towards the instantaneous - not the retarded - position of the source."

IMO the result does not prove anything. You could write: This mathematics shows that etc. IMO if you want to prove something you have to perform an experiment.

For example.
Consider a spaceship at 1 light hour distance from Earth. The spaceship is electrical charged. The spaceship is mounted with a clock.

At Earth there is an Observer.
The observer has a detector to detect Electrical Force resp Electrical Field.
The observer has a detector to detect Gravitational Force resp Gravitational Field.

At the initial state the space ship is at rest.
At 9 we accelerate (event 1) the spaceship such that it moves in a circle around the Earth.
At 11 we decelerate (event 2) the spaceship such that again is it at rest.

Q1 What will the Observer See.
IMO the Observer will detect the two events at 10 and 12.
Between 10 and 12 the space ship moves from the point of view of the observer.

Q2. What about electrical Field.
IMO for Electrical Field and Force the same applies. Before 9 the Electrical Force detector will point to the instantenous position.
From 9 to 10 to the retarded position. From 10 to 12 the detector will move. After 12 the detector again points to the instantaneous position.

Q3. What about gravitational Field ?
If we assume that gravitational Field propagates instantaneous than the Gravitational Field detector should move between 9 and 11
If we assume that gravitational Field propagates at c than the Gravitational Field detector should move between 10 and 12
Other results are also possible.

IMO the true issue is the disturbance in figure 3 at page 3. This disturbance propagates at c in the case of an electrical field.

The issue is at what speed this disturbance propagates in the case of a gravitational field.

IMO it is not possible to perform any test as accurate enough to detect this disturbance
a. for electrical field.
b. for gravitational field.
