I have difficulty believing it. Since electrons have non-zero
rest mass, their motion in any medium at the speed of light 
should (may) produce enough heat to locally ionize the medium.
Wouldnt the electrons be lost in recombination ? The other
thing that is puzzling me is: how does one measure the speed
of something that is travelling faster than light ?

You mean most incompressible after black holes :-)
