Almost every time when you flight to Central America. The airport in Guatemala and Tegucigalpa, Honduras. Both are very old and landing requires skills. TGU or Toncontin is used by AVIANCA/TACA to train their pilots because it is very difficult to land there. Sadly

the level of risk went down 4-5 years ago. They added more than 300 meters of runway. American/TACA/LAN/Delta/United flight there.
