This product presents twenty 1/72 pilots from the mid-chest upward.
This model is printable in versatile plastic and professional PA12 material (for robustness) and fine detail material (for fine detail and smooth surfaces, at the cost of being more delicate and maybe forming crystals). Just snap one off the base, trim to fit the aeroplane cockpit, and glue in place.
Also available in 1:64 scale, where you get sixteen pilots instead.
