Outwardly, Santa Paula Airport (SZP) is not a place that radiates youthful energy. Across the freeway from a town straight out of an old-time Western movie, the hangars are a reminder of a different time, with metal roofs slowly yet steadily rusting away in the foothills of California’s southern mountains. Walking onto the ramp, you might expect a tumbleweed to blow right by you. But when one of the hangar doors begrudgingly creaks open, a different image unfolds.
