The Federal Aviation Administration's decision to ground all flights nationwide for several hours on Friday threw the US sports world into disarray, leaving NBA, NHL and college teams scrambling to reach their destinations in time for a packed weekend of games.

Transportation officials cited extraordinary circumstances" caused by communications issues at regional air traffic control centers for the stoppage. Some teams were left searching for hotel rooms, others rescheduled flights, leagues adjusted start times and several college football programs took the unusual step of chartering buses rather than waiting for the ground stop to end.
