RCSS-Taipei SungShan airport. This used to be the main international airport for TPE. But when RCTP opened, all international traffic moved with it.
However, in some rare occasion, there are aircraft such as MD-11 and 747-SP does use the airport.
2 years ago, a china airlines MD-11 was diverted to RCSS due to fog at RCTP.
There is a street right at the runway threshold. You are about 200-300ft away from the aircraft. Also, you can stand right under the path.
