The Lessons of the Seattle Plane Crash
It’s not possible to eliminate all risks from modern life—but airlines and regulators work hard to reduce them after 
each new incident, anyway.

Modern life is full of potentially terrifying “What if?” possibilities. What if a pharmacist decided to substitute 
morphine pills or strychnine for the next prescription you pick up? What if a school-bus driver decided to swing the 
wheel, and plow a full load of children head-on into incoming traffic, or off an overpass?

What if a FedEx or UPS courier decided to deliver a box full of explosives, or anthrax spores, to an office building, 
rather than business supplies? What if a disturbed student, teacher, or parent walked into a public school and opened 
fire on everyone in sight?

The last possibility is a reminder that there are risks some societies will define as acceptable. All the rest 
illustrate the reality that our lives hang by threads that someone else could decide to cut. The ability to inflict 
harm, whether intentionally or accidentally, rises more or less in pace with the technological complexity and 
interdependence of modern life.

Every modern city dweller depends for daily well-being and even survival on systems that make up the hard and soft 
infrastructure of society: water, power, sanitation, public health, and on down the list of services no one notices 
until something goes wrong. Most are run by people we don’t know, whose competence and good intentions we have no 
choice but to take for granted. As for people determined to do harm—the pharmacist who wants to poison customers, the 
bus driver intent on suicide—the only absolute protection would be surveillance and regimentation on a draconian 
scale. (Want to avoid the risk that any bus driver, ever, could do something rash? Send them all through full FBI 
criminal-background checks, plus psychological testing, and then staff every bus with both a driver and a co-driver, 
each to keep an eye on the other. Any school system could do this. None that I’m aware of does, since it would price 
bus service out of the realm of practicality.)

Thus sane approaches to security have been careful to set the goal of reducing risks, rather than eliminating them. 
The first is possible, and it naturally leads to discussions of cost, practicality, and the trade-offs between 
security and liberty. The second is in most cases impossible, and it naturally invites “security theater”-style 
posturing in fending off threats, and “How could this have happened???” overreaction when something inevitably goes 
wrong. (For more of The Atlantic’s case against security theater, especially involving the early years of the TSA, 
see pieces by Jeffrey Goldberg here, here, and here, and by me here and here. )

So we come to the bizarre, frightening, and tragic episode on Friday night in Seattle, in which a ground-staff 
baggage employee of a regional airline got into an empty twin-engine turboprop, started it up and took off without 
permission, flew dramatic aerobatic maneuvers over Puget Sound, and then crashed on an island off Tacoma, killing 
himself in an apparent suicide.

Bizarre, frightening, and tragic this certainly was. But was it a sign of an alarming failure in security practices, 
as some press accounts immediately asserted? (For instance, from the United Kingdom’s The Telegraph, soon after the 
event: “It has raised fundamental questions about airline security at America’s major airports after the mechanic was 
able to board the plane, taxi onto the runway and take off without being stopped. Aviation experts questioned what 
the authorities would have been able to do if the pilot was determined to fly the plane into a city rather than do 
loop-the-loops.”)

Maybe this will be the appropriate response when more facts are known. For the moment, as is usually the case with 
aviation disasters, many of the most important questions about what happened are impossible to answer right away. 
Here are some of the aviation details, known and still puzzling, and then my hypothesis as to how this could have 
happened. (I trained for and got my instrument rating at Boeing Field in Seattle in 1999, and flew frequently in 
Seattle airspace when I lived there in 1999 and 2000.)
