That's nasty @SlideShare ... you give me an "export" with download links that require me to download each of my presentations one by one, because JS, instead of just allowing me to curl them all.
@my3rdeyeopen@jacuzzi_toaster@SlideShare I have honestly reviewed all the data in the book you cited or any other flight claimed to prove flat earth. It always came down to:
a) connecting flights via major hubs using unrelated routes
b) great circle navigation
wow.. you now need a payed subscription to download presentations uploaded to @SlideShare .. quite a d*ck move as this was once part of @LinkedIn and free..
