THU. OCT 19, 2017 - DAY# 10 OF SAFARI - ZURICH, SWITZERLAND TO NYC - We had landed in Zurich, Switzerland at 6:15 a.m. from Nairobi, Kenya. We told Jo & Jan "goodbye" as they were flying from Zurich to Dulles (Washington, D.C.) airport.  Our departure included passing through security again (even though we landed in a secure area & remained there the entire time,  and then departing at 9:50 a.m. for New York, JFK, with a scheduled arrival  at 12:35 p.m.  (When we finally arrived at JFK it had been 24+ hours since we had departed in Nairobi.)  All went as planned.
