Hope you don't mind two favorites, and they would be KNEW (New Orleans Lakefront) and KMSY (Louis Armstrong Intl), my hometown duo.
I remember as a pre-teen boy hitchhiking to KNEW just to be around aircraft. WWII had recently ended and a myriad of aircraft were spotted around the field. To name a few: PBY's, P-38's, P-51's, A-26's, C-46's and 47,s along with a variety of primary, basic and advanced trainers. Two of the P-38's were dolled up in racing livery. The P-51's were LAANG property.
Most of the adults who worked in the hangers enjoyed having my friend and I around but you also had the occasional grouch. I have a dozen or so of old photos I took of some of those aircraft around here somewhere. If I can locate will post some in this thread.
Airline operations prior to your DC-4 was out of KNEW, but with 4 engine service longer runways were needed. I was at the inauguration of KMSY in 1946 and just about every WWII aircraft was on display...the crown jewel, the B-29. If my memory is correct, the guest speaker was Jimmy Doolittle. From 1959 until 1972 My wife, boys and I lived a mile or so north of the N-S runway. When those old Lockheed Constellations passed over, it shook the dishes in the cabinets. AH, the memories.
