Ben, I was looking around flightradar24 and noticed they (whoever they are!) were out flying their magic balloon that defies the prevailing winds and brought it up over your spread. What
were they looking for?
On another note, that thing has been hanging around 60K for a few days now and meandering west, I wonder what it really is and what kind of payload it carries.
OK, that's my musings for tonight.
