Height 35000 ft * 1.5 = 52500

Square root of 52500 = 229.13 miles.

Specsavers have their own aeroplane so their pilots should see further than most.

If its day time and he can see the sun, 91,000,000ish miles

and if its night, and he can make out the Andromeda Galaxy 17,048,013,582,232.462(very)ish miles....

....and if he is on his tiptoes, probably a wee bit farther
