primary Air Force Two aircraft. Being a private plane, the Gulfstream's call sign was Executive Two while Rockefeller was in office. On February 2, 2000, a bill was on the Senate agenda that looked as if it might end up in a tie, requiring the vice president to cast the tie breaking vote. A US Airways Shuttle flight was the fastest way to get from New York City, where Vice President Al Gore was, back to the Capitol. As it turned out, his vote was not needed. If the vice president's family members are aboard, but not the vice president himself/herself, the flight can optionally use the callsign Executive Two Foxtrot just like Executive One Foxtrot.
