Completely normal. Happens all the time. My plane was delayed this week because of an unruly passenger on the plane before mine at the gate. My plane had to be diverted into another state while they sorted him out. The day after I landed, I was walking to get something to eat, and there was a bum fight at the road entrance of a Target. They had a disagreement about who could panhandle there. On the way home, some guy climbed the fence and got on the runway. They don't know who he is though, he was sucked through the engine of a plane.
>Friday’s episode at Denver’s airport came one day after a Delta Airline employee died on Thursday night at Orlando’s international airport when a vehicle struck a jet bridge next to an airplane with passengers onboard, as the local news outlet WESH reported.
>Meanwhile, on 3 May, a United Airlines plane arriving in Newark, New Jersey, from Venice, Italy, clipped a delivery truck and a light pole, which in turn struck a Jeep. Only the delivery truck driver was injured, but the plane was damaged extensively and the NTSB classified the case as an accident while also opening an investigation.
From the article. "Rare" occurrences... three times a week. In the meantime, Japan runs an airport for 30 years and never even loses one piece of luggage. The US is not on the same level as Japan. Any insistence otherwise is just cope.
In particularly bad neighborhoods in the US -- it happens sometimes.
Depending on what kind of life you live in the US, it could be completely foreign to you, or it could be normal.
