I have lived here all my life and I was an adult when Kennedy was killed. I don’t remember International being added to our airports name until it moved to its present location in ‘69. If this guy was military he would have come into Ellington Field which was not close to the Shamrock either. I am not saying I doubt this guys story entirely (I only skimmed it) but the airport/hotel part seems confused. The Shamrock Hotel was torn down 20 years later so I am not sure if it was still a classy place to stay at this time or a dump.
I do remember Kennedy being filmed coming out of the Rice Hotel in Houston the day before he was killed in Dallas. My husband made the remark “I am glad Kennedy is leaving Houston I have a bad feeling about him for some reason”.
In 1977 when I transferred to Houston it was still considered a classy place
I think it was the Shamrock, which had been maintained awhile. I think Castro stayed there too.
Maybe that can be a conspiracy as well.
I remember seeing the Rice Hotel footage, too - but lived in OK at the time. Only later did I learn that JFK hadn’t even spent the night here - just used a Rice suite for changing clothes before a speaking engagement, then jetting on to Foat Wuth for the night.
