Just a counterpoint for those who think BC does not suit Mars. Large lakes are everywhere in BC, Pitt, Harrison, Chilko, Shuswaps, Christina, Francois, Sproat, Tatlayoko, Anderson, Puntzi, Stum, Ahbau, Fraser and many more are all large enough for Mars. As someone above posted the US has DC-10 & 747 for runway ops, however with the massive amount of lakes in BC & Canada (most lakes of any country in the world) create an opportunity that many other regions do not have. All the lakes listed above are less than 200 miles form fires which are or have been burning this year. Some are right beside such lakes in fact. 6200 litres in a 415 vs. 27200 in the mars. The old gal has it's strengths and at over 4X the capacity of a 415, it can accomplish it's mission quite effectively.
