One a year when I worked for an Oil Company.
Each Medical re-issue.
A couple times driving from Los Angeles to Lake Havasu.
Did I misunderstand the question?
I think so, yeah. A few people misunderstood, I wrote in the first sentence "in flight,.." But I don't mind. Car pee stories, urine test stories, it's all good.
When I was a little kid I had to a few times while flying with my parents. My mom had a large Teflon "bottle" that I had to use, but it looked (or was for all I know) the same as what she used to keep orange juice in for breakfast. After the first time I must have had a subconscious aversion because I decided I didn't like orange juice.
Now, just starting learning to fly I had to go to my first flight medical. Eye doctor before that, etc. and had a lot of time to kill. I had had a few cokes, and water...had a hard time finding the flight doctors office as it wasn't marked and was just inside an emergency room, doctors office. So when I got there I really had to go. Wasn't sure I was in the right place, and there was a bathroom and i didn't think about the consequences but just used it.
It was the right place, and after questions and some tests she hands me the little cup. I tell her I did a dumb thing and just had gone. Try anyway, drink some water was the advice. I go in the bathroom and drink about ten cups and nothing. No way. I come out after trying for fifteen minutes, "no luck". Oh well, she says "we still have a number of tests and we can do those, you can try again later". So we do.
Later I repeat the process, ten fifteen more cups of water, thinking about waterfalls, let the two run in the sink, nothing.
Been there for hours, and the nurse and Doctor say "well, what do we do now? Listen were open for three more hours, go out and take a walk and see if that helps". This place is a good distance from where I live and I really don't want to have to come back another day. I walk a few miles, drink more cola, a cup of coffee...hop a little on the way back. Am pessimistic.
I go back in, go into the bathroom and viola! Sweet success!!! I'm so relieved (sorry about the pun) I come out with the urine cup in my hand, see her across the way and say "YES!!" with a big thumbs up and only then notice another patient sitting there looking at me strangely.
I had started getting paranoid that maybe they thought I was not taking it on purpose because of drugs or something. But all is well, we sign my med. cert. And I drive home....in heavy traffic...and within ten minutes on the stop and go traffic on the freeway... I REALLY have to pee.
I barely made it home about 45 minutes later.
I fold up th med. cert. To size and go to out it in my kneeboard to have with me on flights, and see that they have my nationality as Norwegian, but I'm a US citizen. Had to send it back, then a copy of my passport, and even then a month later they need even one more copy of my passport, but it is now in order.
When it rains it pours.
