Topic: Composite Aircraft

Flights in Phoenix were grounded during a record heat wave, officially attributed to changes in air density affecting lift. However, alternative theories suggest that modern composite or "plastic" planes face structural risks on the tarmac when temperatures exceed 130 degrees. Older sheet metal aircraft with rivets are reportedly less susceptible to heat-related safety issues than newer composite models.

Wichita, Kansas, is highlighted as a major aviation hub due to its inland location, which historically protected it from coastal bombing. Local engineers express skepticism regarding composite "plastic" aircraft like the Boeing Dreamliner and Airbus models, claiming they cannot operate in temperatures exceeding 125 degrees. The travel log concludes with a culinary note on Salvadorian pupusas found in the city.
