‘Retractable Skidded’ AH-1 Cobra When Bell first came up with the efficient and versatile Bell AH-1 Cobra combat helicopter design, it originally went one step further by incorporating a retractable skid arrangement. This arrangement featured the skid’s retracting into the narrow fuselage. I...

Here's the Cessna 308:
