I think you're out by a factor of 10.... 267*10^9 bytes, divide by 10 as
there are 10 bytes to the inch on paper tape, and convert to miles. I
get just over 400,000 miles.

My rule of thumb is that a full reel of 1" paper tape is 100k bytes
So 10 for a megabyte
10000 for a gigabyte
2,670,000 for all of bitsavers. Perhaps nearer 3 million as it's an
approximation....
