Explained in plain English

Are all planes built in the US?

Not at all! While Boeing is a major US manufacturer, many other countries build planes. Airbus, a European consortium, is Boeing's main rival, producing aircraft in France, Germany, Spain, and the UK. Brazil's Embraer and Canada's Bombardier also build significant numbers of planes, highlighting a truly global industry, even if US agencies get involved in incidents like the Ryanair one.
