Well this doesn’t sound like a very good idea.

Pope Francis’ flight from Cuba to Andrews Air Force base — Alitalia 4001 — is  not being blocked by online flight tracking websites, thus allowing anyone to track the pope’s flight in near real-time (data is delayed up to 5 mins. in the U.S.):

We assume the 5-minute delay is enough to make sure the plane is safe — at 400 m.p.h., this is about a 30-mile difference from its actual position — but it does seem odd that the plane’s progress would be this public.
