In my story, a very small percentage of individuals develop superpowers (about 1 in every 10 million, if not less. There are about 200 billion people in this world). Everyone else in the world is entirely normal by human physiological standards, though this is a very advanced civilization (estimate around 2200 or so, mankind is now interplanetary.) There is an organization made up of these individuals and select normal humans who know about this, and the superpowers need to be entirely kept secret from the larger human population. The superpowers can develop spontaneously, and no activation trigger is known. This society is also very small in comparison to the larger world, though not as small a percentage as those with powers.
There are no dowsers- in other words, it's impossible for a powered individual to detect another one or the development of one. We're assuming that if, once in a while, a person (who's not affiliated with the organization, possibly because powers just developed) triggers abilities in public and it gets on the news or something, mankind is not stupid and will not just fail to notice these superhumans disappearing soon after they display activity.
How does the organization locate and retrieve all individuals who exhibit powers, without the public noticing?
Bonus question that's entirely unrelated: Find a name for a jetpack similar to the EXO-7 Falcon from Marvel, that conforms to the acronym H.A.W.K. and actually makes sense without making it sound like too much of a stretch. (So far, I have High-Altitude Wing-based _______...the K is hard...)
