The scene: It's the late afternoon. I get on and take my window seat.
Passenger description: Well, see for yourself.
The review: So, this grasshopper (?) was apparently living IN BETWEEN THE PANES OF GLASS in the window of the plane. Just to be clear: in between the tough plastic double glazing, which is supposedly air tight. There's no way in there, nothing to eat and no way out. These questions presented themselves: How did this insect get in there? Did it hatch from an egg inside the glass? How is it sustaining itself? How long has it been there? How is it breathing? I thought about these things for the 90-ish minutes of the flight, alerting neighbouring passengers and cabin crew to the stowaway. No-one had any idea how it could come to be there. I couldn't take my mind (or eyes) off it. It seemed happy enough. I don't know. It's hard to tell with insects.
Verdict: Baffling. Innocuous and sinister at the same time.
