We analyze the data on the comparison of clock rates between a ﬂying clock and a clock at ground, carried out by Alley and coworkers at the end of ’70’s. The fit to such data is in favour of an energy-dependent metric for gravitation. We discuss also the results of a recently proposed electromagnetic test of breakdown of local Lorentz invariance -based on the detection of a voltage induced by a stationary magnetic ﬁeld- and show that the obtained positive evidence for such an effect seems to support the derived form of the energy-dependent gravitational metric.
