U.S. taxpayers spent nearly $16 million to fly the Obamas on their vacation to, from and around Hawaii and Africa, Air Force records show.

Hundreds of U.S. Secret Service agents will be dispatched to secure facilities in Senegal, South Africa and Tanzania. A Navy aircraft carrier or amphibious ship, with a fully staffed medical trauma center, will be stationed offshore in case of an emergency.

Military cargo planes will airlift in 56 support vehicles, including 14 limousines and three trucks loaded with sheets of bullet­proof glass to cover the windows of the hotels where the first family will stay. Fighter jets will fly in shifts, giving 24-hour coverage over the president’s airspace, so they can intervene quickly if an errant plane gets too close.

The elaborate security provisions — which will cost the government tens of millions of dollars — are outlined in a confidential internal planning document obtained by The Washington Post.
