That is a strange looking turning circles graph..

Altitude vs. Radius?

Where alt units state ('000 ft)

Something is strange here.. as in some info is missing (calc at a fixxed speed?)

I mean based on that graph the Spit is not able to go above 700ft in alt?

At a glance one might conclude that the Spit and Hurry have better turn radius..

But it is allmost as if that was done on purpose..

Does the book say more about that graph and how Mr. Ackroyd calculated it?
