The BU60-1 balloon attained an altitude of 53.0 km (32.9 mi; 173,900 ft).
Weather permitting, would a series of climbable balloons in a chain be able to be linked from the ground to that height of 53 km?
To gain altitude each balloon must be gradually bigger.
At the bottom balloons would be made of more durable material.
I have found no record of this being done with higher tech weather balloons.
