Haven seen anything about them in UK papers or Canada
—
On of the most famous incidents occurred on an air base in the UK; Canada has had lots of incidents; Mexico is a hot bed, as is much of South America and Antarctica. Russia has long been investigating UAPs. They just are not reported to news papers - you have to go to organizations which collect those sightings. People say little or nothing because they are ridiculed, called crazy, by others who are ruled by fear of the unknown.
UK; Canada has had lots of incidents a lot of people see things when it’s not really what they think they saw.
Yet no parts or evidence it’s drones at best.
