If the reason these two spacecraft appear to be short of where they should be is that they are moving away at a critical speed then is it reasonable to assume that something moving towards us at the same speed would also appear to not be where it should be, but in an opposite sense?
There is no scientific principle to justify this thought but it is interesting and what would the consequences be if it turned out to be valid.

The spaceship would be shorter only in the direction of motion. You would not see a difference if it is moving toward you.
@Bracewell,
Vectorcube - Perhaps I have not made the question clear. Pioneers 10 and 11 are not where they should be assuming the speed and time they have been travelling. Their speeds are far too slow to expect measureable dimensional changes. See Wikipedia Pioneer Anomolies.
