$17,870 | 800 | $14,089,363.3 | $31,788,189.7 | $1.87 |
Lacking
the length of the ropes exactly right.
Bursting
fold and roll the balloons that would distribute the stress more evenly across the fabric to pin the leaks while transporting.
Leaking
Gas cylinder maintain the volume.
Temperature Problem
