Sleep in a plane
It wasn’t until my last trip in early 2015 that I actually felt relaxed enough flying to fall asleep. Of course added to that is that I didn’t have anyone sitting near me on the flight home. Plus I had a few beverages to drink and I was thoroughly exhausted after getting up early and getting ready to go home.
I think it means I’m finally getting used to flying on a plane although it still feels so unnatural to me to fly so high in the air with absolutely no control over it. Not that you have that much control in a bus or a train but it probably has much to do with control freak tendencies as anything else.
