You are correct that the box is nowhere near the 5 feet tall I assumed; probably more in the 2-3 feet range.
The helium in the 5 tanks using Jet's dimensions still takes up the same space. There is less space left over, but still plenty IMO.
Just think logically. The tanks (or a single larger tank) occupy the bottom of the box to a heighth of 9.25". The remainder of the box is available for the blimp and the tether.
