Correct! An hour and a half!
Furnace Creek (L06) is a place of superlatives. The lowest airfield in the Americas at 211' and the place where the hightest temperature ever recorded in the US at 56 degrees C in 1911.
Also, it's one of the few airfields in the US where you have to pay a landing fee. Although technically, it's the fee payable by any vehicle visiting a National Park. But your $5 also includes free access to the excellent visitor's centre, so it's good value.
You have control.
