No, the Sicard was a giant brush with a blower behind it, normally towed by a Bedford truck. Very effective on soft snow or after the snow ploughs had done their job. The brushes were originally made from hardened spring steel and became detached very easily. A wonderful FOD hazard afterwards, hence the Airfield Sweeper had a huge magnet slung across the back about 2ins above the ground.
MRDs were also known as Machine Runway DESTROYER, many a time I watched chunks of asphalt fly away in addition to the ice!!
It seems that we had more snow "in the old days" and we were spoilt with loads of available manpower and no apparent budget constraints, and, of course minimal H and S impact.
