Just looking around on flightradar24 , and came across what I suspect are two balloons HBAL 421/419 showing an altitude of over 60000ft traveling at 7 kts, just up from Las Vagas, not seen balloons before, there was three but one has gone missing, what do you think weather balloons.
I had seen the loon project, but could not see why they would fly two balloons next to each other, but it would make sense to be able to locate them if you are trying to connect to them.
