I too would like to see much more experiments done.  In different tilts, and different elevations.  At different times of the year, full moon, new moon.  At different latitudes.  Maybe we could build one into a smart phone and take readings everywhere.  And then send it into space.

As long as they actually report the readings.  As Michelson & Morley found something... and then called it an error.  If we had lots of readings from all over, we could have found out something spectacular about our planet and space.  But, the "scientists" said, there is no aether, no wave pattern, and put case closed.
