You can, it’s just usually zero, which is what I think the comic is suggesting
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
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
