I've only been in one on commercial flight, in Costa Rica (SJO) in an A319 or 320. During the rainy season, there is usually rain beginning in the early afternoon from an hour or two to several hours. And the clouds get very low.
We were landing about 3pm I think. I kind of expected some of what happened. So the approach is white out the whole way, can't see a thing. Thick white clouds. The gear comes down and still can't see a thing. As we get closer and closer, I start to get a bit nervous seeing how I can't see anything but white (and grey). Then we are low, maybe 100 feet AGL, and I see the runway threshold zoom by and then thousand footer (so we are not on centerline--I should not be able to see the thousand footer if we are lined up). And we are still descending. Now, I'm starting to freak a little. This guy is going to land halfway down the runway. I know it's 10k feet but it's been raining all afternoon, not the best time to practice hard braking. LOL (I remember turning toward my buddy and telling him that this idiot is going to try to land halfway down the runway or something like that)
Finally, as the wheels are about to make contact with the ground, we heard the engine throttle up and it got loud and we started a steep climb (or maybe it just felt that way). Any way, we circled for about 45 minutes but the weather would not give, so we had to go to our alternate Panama City to refuel. After the refuel, we waited there for about another hour until we got the go-ahead to return to Costa Rica. The low cloud cover was gone and we landed with no issue. I don't know what could've happened if he had tried to land and stop on that wet runway with 5 or 6,000 feet to go. Or is that plenty for a 320 to stop, even in pouring rain?
