William Robert Johnston Municipal Airport serves Mendota, US.

William Robert Johnston Municipal Airport (KM90) in Mendota, US, is closed indefinitely as of June 2025, with a drag strip having been constructed on its runway. Therefore, recent traveler reviews and experiences for this facility as an operational airport are unavailable. The information below reflects historical characteristics and the current status, rather than contemporary traveler sentiment.

What Travelers (Historically) Might Have Appreciated:

  • General Aviation Focus: As a municipal airport, KM90 primarily served general aviation needs.
  • Basic Pilot Amenities (Historically): While it was often unattended, historical records indicate the presence of a pilot's lounge and restrooms, along with access to weather and flight planning resources.
  • Fuel Services (Historically, but contested): Some historical information suggests the availability of fueling services (Avgas and Jet A fuel), although another report from 2021 indicated a lack of fuel at the airport.

Common Complaints (Historically and Currently):

  • Indefinite Closure: The most critical current "complaint" for any potential aviator is the airport's indefinite closure since June 2025, with the runway now used as a drag strip, rendering it unusable for aircraft.
  • Poor Runway Condition (Historically): Prior to its closure, the runway (15/33) was reported to be potholed with areas of collapsed pavement, and the parallel taxiway had a rough and uneven surface requiring extensive asphalt repair and patching.
  • Unattended Status (Historically): The airport was described as unattended, which could have led to a lack of immediate assistance or comprehensive services for pilots.

In summary, William Robert Johnston Municipal Airport (KM90) is no longer operational for aviation purposes due to its indefinite closure and conversion of the runway into a drag strip as of June 2025. Consequently, there are no current traveler experiences to review, and any historical positive aspects are now superseded by its non-operational status for air travel.
