Homeless and at the airport

There are dozens of airports that serve as sleeping pads for the homeless. Some airports are more tolerant than others when it comes to the unexpected tenants.

One would not necessarily think of an airport as a place to land for the evening, with the bright lights and the usual noise, but often the homeless choose to opt for the airport as it can be a lot safer than homeless shelters.
