Yup I just returned from Grand Canyon Airport in a 109hp cessna 140 and it’s amazing how different landing/take off are at that altitude even without scorching heat. I’m used to sea level so I had to keep a ton of power in even on final just to keep the wings from wobbling. And the groundspeed on touchdown makes it really interesting when you’ve got a crosswind.
I envy your ability to fly to the Grand Canyon. On my bucket list is one more flight to the Canyon.
The best time to see the canyon is at sunrise, BTW, so if you get back up there, take the dawn patrol - you will not regret it.
As you know, fixed wing flights into the canyon are no longer legal, but I was fortunate enough to live in Flagstaff and be able to fly many charter flights INTO the Grand Canyon between 1975 and 1981 - I’ve flown into the “inner gorge” many times - BEAUTIFUL MEMORIES!
