However, with no room to navigate up the steep glacial valley, the pilots finessed the airplane over the hurdle with no more than 200 ft of clearance. Every pilot knows that aircraft fly because the forces of lift and thrust balance or exceed the weight and drag countering them.

These include lift, propeller thrust, and engine combustion. For example, if we were to takeoff on an airfield at sea level at 0C (32F), it would take 1520ft to reach our obstacle clearance height of 50ft. Whereas for the same airfield on a different day, if it were 30C (86F), that same obstacle clearance height would take 1880ft.
