Input: Text: this happened to me a couple of months ago, when i was on a flight by myself to london, en route to australia.

my plane was leaving from helsinki, which is a clean, modern, spacious airport. i checked in early and did the usual snack/drink/internet routine before embarking. i had with me quite a big of luggage, since i was moving to australia to live there. 

as i board the plane, i sit down next to a well-dressed businessman. he's got the financial times and his laptop is open ; he's probably  responding to a couple of emails before the plane leaves. he resumes doing so after the seat-belt sign goes off, so we don't have the opportunity to talk during the flight.

i look out the window a little bit, day dream, and doze off quietly after that. i wake up 10 minutes before we land. the plane taxis to its terminal at heathrow, and we all stand up to leave the airplane. i check for the newspaper and my passport.. i find the former in the seat pocket in front of me, but not the latter. no big deal, my passport is probably in some pocket of my pants. check that, nope. on the floor beneath the seat? nope. in my bag? i take everything out, shuffling the pages of every book and newspaper. still nothing.

at this point, practically everyone has exited the plane. i walk over to the steward in the front of the airplane and tell him i can't find my passport anymore. we double-check everywhere. they call in the cleaning crews that disassemble the seat where i was at to make sure it hasn't fallen in one of the cracks. ditto, still nothing.

i'm parsing everything i can remember doing during the flight, but nothing seems out of the ordinary. i vaguely remember having my passport with me at the beginning of the flight, but that's about it.

i'm starting to get nervous and ask the stewards what to do. they've never had to deal with this before. they call somebody up from security. same reaction, he has no clue what to do. they tell me to go to the passport checkpoint and tell them what happened. at this point, i start feeling a bit awkward, like they want to get rid of me because they sense how weird the situation might end up being for them. in a pleading voice, i ask one of them to come with me to the passport checkpoint to corroborate my story, just so i won't look like a fool or a crazy man at security, but they politely refuse.

when i arrive at security, i try to muster a cool, explanatory voice, without showing that i'm starting to freak out. the border control agent asks nicely a couple of questions, looks at me incredulously and goes to get her supervisor, a tall man in his mid 50s. he seems to think i'm either a complete moron or trying to hide something from the police of his country. he starts asking questions in a loud, aggressive manner :
- "so how did you get on this plane without a passport? can you explain that to me?"
- me, trying the best to defuse the tension "i had the passport when i came in sir. i can't explain how i lost it. it just wasn't there when i was looking for it. i asked the steward, the cleaning crew came.."
- "shut up! you're lying. where's your passport?"
- i'm trying my best to act in a cool tone, just stating the facts. at this point, heads start turning because he's talking more loudly at each sentence. me "you can call the airline, they'll confirm my story."
- him : "i've had enough of this nonsense, you little prick!". he steps out of his cubicle and grabs me by the arm and shoves me in a waiting place in the middle of the immigration zone. i'm sitting with what seems to be a pakistani family, a couple of young men from sub-saharian countries and an old chinese man (who later leaves to go to a booth with a translator)

we're waiting here indefinitely. i weigh my options and think of using my computer to skype the french embassy in london to inform them of my situation. that's when i remember that i have a copy of my passport on my laptop. i wave at the supervisor and tell him i have a copy of my passport. he comes back 5 minutes later and takes my laptop with him. he hands it back to me 10 minutes later and asks me to wait in the waiting lounge again. the people there seem to have lost track of time as they've probably been waiting there a long time.

quite rapidly, the supervisor comes back with a contrite smile, excuses himself for yelling at me (he explains that he thought i was trying to make a fool of him) and tells me i can leave.

the only problem at this point is that i'm taking a flight the next day to leave for australia ... and that i don't have my passport. i'm in a foreign country with no formal identification. by then, it's friday afternoon, and i can't go to the french embassy in london till monday morning to get some sort of temporary identification to be able to travel.

at this point, i remember that the stewards showed me the passenger list and the name of the person sitting next to me. now that i think about it, he was the same nationality as me, french. maybe he saw my passport, mistook it for his own and took it with him as he was leaving the plane.

i search him up on internet and find out that he works for a large bank in london. i send an email to my dad who happens to know some people who work at that company. within 30 minutes, my dad finds out who that guys' boss is and explains him the situation. about an hour later and a couple of emails back and forth, i'm able to get in touch by email with the person who was sitting next to me. 

it turns out he had taken my passport inadvertently with him as he left the plane. we agreed to meet up later in the day so he could hand me my passport and i was able to fly to australia with my passport.

i guess the moral of the story is to always have a digital copy of your passport on your computer when you travel
