ASSUMPTIONS:

(A) Launch at 02:30 UT from Koln
(B) Landing NO LATER than 14:15 UR at Dusseldorf
(A) Mid-eclipse centerline intercept 09:43 UT
(B) True Ground Speed = 483 nm/hr
(C) No wind
(D) Totality Run Start 6 minutes before mid-eclipse (MINIMUM*)
(E) Totality Run End 3 minutes after mid-eclipse (MINIMUM)

 * For pre-totality portion of run 9 min would be preferable, but
   for conservatove planning purposes 6 is used below.  This is
   open for discussion to trade run-start time for contingency time.
