No, coaches did not use hovercrafts in the 1970s. Hovercraft technology was still in its developmental stages during that time and was not widely adopted for transportation, especially in sports. Coaches typically relied on traditional vehicles like buses and vans to transport teams. The use of hovercrafts for coaching or team transport remains largely a fictional or novelty concept.
