In ancient Greek mythology, Daedalus built the famous Labyrinth in Crete — and was later imprisoned in his own invention. (We’ll come back to that in a minute.) Ever resourceful, Daedalus made wings out of feathers tied together with linen threads and fastened with wax. Rising on their wings, Daedalus and his son Icarus escaped the Labyrinth. But you all know what happened next. Icarus — not hearing his father’s pleas (or, more likely, simply ignoring them) — soared higher and higher. Soon, the blazing sun melted the wax in his wings and caused the feathers to loosen and fall. Though Icarus continued to flap his arms, they no longer caught the wind, and the poor boy plunged into the sea. In the language of engineering, Icarus exceeded his thermal limits —leading to structural failure and a subsequent loss of control.
