Once flew on a Cessna turboprop aircraft to Maine to meet a friend who was hosting a gathering at his home. Got on the plane without a phone (this was 1984, when cell phones weren't everyday items) with about $40 cash in my pocket. The plane landed at a different airport than my destination, and said I'd need to call my friend for a ride. Right. Didn't have his phone number, and I was stranded for 90 minutes until my friend figured out where I was by himself (no clue how he did that, likely he was waiting at the correct airport and when I didn't show up, he began asking questions), drove 50 minutes, picked me up, and we drove to meet his fiancée at his home.
Met some of my high school buddies there and we stayed the weekend. Hiked up a mountain in Maine, viewed Ghostbuster's when it first debuted, had a few meals and drinks.
I recall his memorable words regarding toasting his imminent marriage Sunday noontime: "Join me in a glass of champagne? Think we'll both fit?"
Flew home Sunday afternoon to the correct airport, my family picked me up and we drove home. Wasn't sure how I ended up in the wrong airport in Maine, but am guessing it was because the pilot serviced the plane where we stopped because it had an issue and couldn't fly to its correct destination.
I guess I felt stupid at the time because I didn't know how to contact my friend who was waiting at the other airport. Thankfully, the plane service forwarded landing info to the correct destination telling them we were safe elsewhere.
