For sure, the scariest landing I've experienced was at Tegucigalpa (Tonconting Airport).
For those who haven't lived the experience, let me describe it. It starts with the plane approaching to a mountain, it then turns left to approach the runway... and keeps turning left while it goes down... and then after some seconds... the thing is still going down and turning.
5 seconds before touching ground it finally stops turning left and lands. It's a unique experience.
To illustrate it, please find below a footage of an American Airlines Boeing 757 (largest plane that can land there) taken from a nearby mountain. Enjoy.
