We took all these suggestions on board, and found further inspiration here, following a tip-off from a reader who reckoned a triangular truss suspended between two balloons offered the best solution.
We were inclined to agree, and in the best garden shed boffinry tradition, set about putting together a model of a LOHAN flying truss.
