You can, it’s just usually zero, which is what I think the comic is suggesting
What if they ascended to normal altitude, then lowered a tether back down to the ground? Probably break some records as the wind swung you down to the ground.
I don’t think that would be level-flight
Tether yourself on three sufficiently far apart points with no slack in the rope, and you will be stationary
It would be wind speed wouldn’t it.
Airspeed of hot air balloons would be very similar to wind speed, except for when there’s a quick change in wind speed as the balloon would have some momentum
