It was also used by the Pennsylvania militia in episodes of the Great Railroad Strike of 1877, specifically in Pittsburgh.

Tambo sometimes flies over the Antarctic Circle to latitude 71 degrees as well and allowing views of the icecap. Qantas also flies nonstop between Sydney and Santiago de Chile, the most southerly polar route. Depending on winds, this flight may reach 55 degrees south latitude, but other times 71 degrees, which is enough to cross the polar ice cap. The polar route across the remote southern Pacific Ocean between South America and Oceania was pioneered by Aerolineas Argentinas, which began service between Buenos Aires via Rio Gallegos to Auckland in the 1980s with a Boeing 747-200 aircraft. Aerolineas Argentinas later operated to Sydney, but ended its flights to New Zealand and Australia in 2014.
