As America awakens to ‘objects’ in the skies, question now is what’s the strategy to tackle them

WASHINGTON – Increased scrutiny of US airspace, prompted by the discovery and

shooting down of a Chinese balloon

on Feb 4, is largely the reason more high-altitude objects have been detected in recent days, say experts.

But US officials acknowledge that many questions remain about the origins and

purpose of three other unidentified aerial objects

that have been shot down over North America in the past week.
