Four Dutch F-35 Lightning II fighters and a tanker operated from the Netherlands’ main international airport, one of Europe’s busiest, during the NATO-led exercise Avatar. Schiphol Airport, located just 9 kilometres southwest of Amsterdam, is one of the busiest airports in Europe. Over the past couple of days, alongside its usual flow of civilian airliners, the airport also hosted some unusually loud and uncommon visitors: four Dutch F-35 fighter jets. “In a crisis or in wartime we might not have access to our own airfields,” Air Commodore Robert Adang, acting commander of the Royal Netherlands Air Force, explained. As a side note, it is also worth noting how much F-35 operations have evolved over the past decade.
