Mike.....et al.......
        This raises lots of questions, does Thrust SST use of active
equipment mean it is allowable in speed events?
.After all, if a LSR is to remain an LSR would it be so if the vehicle
was off the ground going through the lights and does it have to touch
the ground ALL the way during the measured mile, so what's the
separation of LSR from ASR ??..........DK.......Well?
