There is a huge Trad mecca in St. Mary's KS. Including a large Resistance location.
There is a lot going on around the East Coast. The new SSPX seminary is in Virginia. Bp. Z has a major chapel in CT/NY area. And there's the famous independent chapel "St. Athanasius" in VA as well.
Not to mention all the possible international flights (say, from France or England) that might end up in Washington, DC, even if it's just a hub or connecting flight.
What if a Dominican priest flew in to the USA to help out at the St. Mary's resistance chapel? Wouldn't he be on a flight exactly like the one that just exploded?
Fortunately, Bp. Z often drives from Kansas to his East Coast destination. Or, he goes there by way of Texas.
But a plane crash of this magnitude is still rather unsettling. Trad priests and bishops spend a huge percentage of their lives on airplanes. At least way more than the average Trad. Think of how many flights/year the average Trad priest takes, compared with the average Trad.
