The 38 is a much better plane in AH. They are similar in that they are propeller driven fighter aircraft, flown by people, using a mix of cannons and machine guns. Beyond that, I'm not really sure what similarities they share. Internal combustion engines and largely metal construction? They catch fire, shed parts, or blow up when shot? They're also arguably similar to school buses in that regard, but I would still hesitate to draw that parallel with a straight a face and any conviction.
