Well, the worst landing I've ever experienced was in my rented Cessna 172N at MBO (Madison, MS
). You know, the usual - landed too hard, crooked, and off-center. I used to really suck at landing, but I've gotten better in the last few months.
The worst runway I've ever landed on was 0M8 (Lake Providence, LA
). Airnav.com described its runway as "in poor condition," with the comment "cracked with grass growing in cracks." It turns out that about a third of the runway at one end was more grass than pavement, and some of the grass was tall enough to reach the prop. While not necessarily a bad thing, it did slow me down, and with only 3200 feet to make a touch and go, I was cutting it a bit close.
On a commercial flight, the hardest landing was DL155, JFK
on June 3, 2003 (DL 767-300ER, originated in VCE). After landing, the pilot said over the PA that the computer landed the plane, which is why it was not as soft as usual - I guess he had to clear his name so he wouldn't get any comments from the passengers about it!
But hey, I've done worse...
