Traffic chopper to tail Easter holiday drivers
New radar system took six years to develop

Motorists on Spanish roads over the Easter weekend could find themselves being tailed from the sky. The DGT highway safety agency on Thursday unveiled a new traffic helicopter radar system, which it plans to put in use during the extended holiday.
The radar, which will be installed in 19 choppers, can measure a vehicle's speed and record video from an altitude of 1,000 meters. DGT director María Seguí said the radar system took six years to develop.
