Head rebuilt skis from aircraft sandwich panels

By the late 1940s, recreational skis were still made from bent and laminated wood -- typically hickory -- the same basic craft that had shaped skis for decades. They were heavy, warped unevenly with humidity and wear, and behaved inconsistently underfoot because no two pieces of natural wood flex identically. Ski makers kept refining that same wood-craft tradition: different species, different lamination patterns, better bending techniques, all still working within what a piece of timber could do.

Howard Head was not a ski maker. He was an aircraft engineer at Martin Aircraft in Baltimore who took up skiing as an adult in 1947, found the wooden skis of the day exhausting and unforgiving to control, and decided the fix wasn't a better piece of wood at all -- it was the same structural problem his own day job already had a solution for: how to build something strong, light, and predictably flexible under load.

Applied aircraft skin-and-core sandwich construction to skis: stiff aluminum skins around a lightweight core, giving consistent flex and much lower weight than wood.

Sandwich panels resist bending like thicker beams but weigh less, giving predictable flex.

Aircraft engineering provided a proven solution to the structural challenge of skis.

Field testing with real skiers refined the design to survive actual loads.

When a craft tradition only improves incrementally, look to a different engineering discipline that has already solved the same structural problem.

By 1955 Head Skis was the leading ski brand in Europe and North America; by 1966 its Timonium, Maryland plant was grossing $25 million a year selling 300,000 pairs of skis into 17 countries, built from a company Head had started with $6,000 in poker winnings. Head skis won medals at the 1964 Innsbruck and 1968 Grenoble Winter Olympics.
