Upon my arrival at Dulles International Airport, my escort met me at the gate with the wheelchair. As we approached the passport control checkpoint, the escort assured me that it wouldn’t take long, due to the machines that scan the passport. Oops! I had informed my father to arrive one hour after my plane landed; more lines with international flights. I need not have fretted, as the machines had some problems.
Problem? An engineer’s ears perk up—something to solve. The engineer’s mind becomes engaged. One could say this engagement is a curse as much as it is a blessing. Engineers have the habit of providing unwanted advice when they see an issue that could be resolved if they just changed “this ‘n that.” I must admit, I fall prey to this habit.
The machine asks for your language preference–mine is English. My escort placed the passport on the clear plate, pressing down quite firmly. Machine attempts to scan and responds, “unable to scan.” Try it again, same response. My escort states this happens a lot and we just need to try another machine. Two attempts again, and no paper to show a successfully-scanned passport. The machines fail to impress me with their quickness, as they have utterly failed to perform a simple scan. Fortunately, people remain as the backup. Workers in yellow vests point us toward the passport control people with a “Let them know you couldn’t get a scan.” As we wait, I pepper my escort with questions.
“You say this happens a lot?”–he nods.
“Does anyone clean the machines?”–he states he hasn’t seen anyone cleaning them.
“Are the machines ever taken down for preventive maintenance?”–he was not aware.
“The machines should be able to put themselves out of commission if they fail to scan for 20 attempts.” I continue, “This way no one goes to a machine that is down and wastes their time.”
My engineering mind persists with questions and speculations. How many failed scans indicate an abnormal problem? Perhaps someone had mustard on their passport. Is the clear plate glass or plastic, as that would inform what kind of cleaning fluid to use? How long has this system been up–over a year? Well, whatever the reason, the system’s performance is sub-optimal. I smile at my escort and tell him “You can take these ideas and submit them, you can take all the credit.”
We roll up to the staffed passport control. I explain to the agent behind the counter why I’m here without proof of a successful scan. Then I say something about the poor system-I’m an engineer, this should be fixed. He smiles because he lives with it every day, then he asks, how did I sprain my left knee. That’s a story for another day.
Have a Productive Day,
