Evidently this is a yearly event about this time of year. I was searching for further info on today's activities and found 2 from previous years. What it is, is a Hurricane Hunter aircraft from the US has an open house at the Manzanillo airport (ZLO). They are probably making stops up and down the coast. Pacific Hurricane season starts May 15 and we are almost there again.
My neighbors have only been to the airport once when we picked up a lost Gringa a few months ago. I figured this would be an education for both of us so of we went combined with a stop in Cihuatlan. The problem was I had no idea this would be so popular and we found 100's of people waiting. The schedule said Noon to 6PM but dignitaries and special people got to take the tour first. Then the couple hundred who got there early had to register, be given a pass and ushered through at 30 in a group. Not only would the wait be well over an hour but standing in line in the sun was not on our to-do-list. So we sized up the crowd, took a few pictures through the fence and headed back north. If I remember next year I'll go later in the day when things have calmed down.
