Because the commie launch site is at 51.6 degrees latitude.
Ours is at about 27 degrees, Cape Canaveral. The frogs
have one in Guianna at about 5 degrees.

Yes I have good upper atmosphere model, part of
which was in the sheet I posted to Mike. Let me
combine that one with the NOAA upper atmosphere
model and Ill offer it to whoever want it.

We've given up some payload to have a 51 degree
orbit. Also the station is high enough to not be
dragged down to quickly by atmospheric drag.

The shuttle is currently the most expensive ride available,
but it is man-rated. spike
