Those members of the squad who stayed in Rio for Sunday night's closing ceremony waved goodbye to Rio on Monday as they enjoyed a party atmosphere travelling with medals round their necks and posing for selfies with their British Airways pilot and flight crew. The U.S. finished with 46 gold medals and 121 medals overall, its 51-total-medal margin over second-place China the largest in a non-boycotted Olympics in almost a century. They won gold medals across 15 sports, more than any other participating nation and bettered their tally from the last Olympics for a fifth Games in a row. He won six in Rio, while Biles and US swimmer Katie Ledecky each won five to lead to lead a big haul from American women.
Britain finished second in the medal table, ahead of China for the first time since they returned to the Games in 1984. USA track star Allyson Felix, now a six-time gold medalist and a victor of nine medals in all, was particularly delighted to learn that women are bringing more medals home to American than the men.
Having exceeded their haul from the London Games of 2012, Team GB brought back 67 medals from the Rio Olympics, with a large number of athletes arriving at Heathrow shortly before 10am.
Mark England, Team GB chef de mission, said: "The reception we have got since landing is overwhelming".
But Blackmun was thrilled by the results, and he wasn't the only one leaving Rio happy.
Rugby and golf, which returned to the Olympic program after a long absence, proved to be successes, although the swaths of empty seats at many of Rio 2016's venues were an indictment on the organizers' inability to market the games to the public.
The Russians and the Chinese probably didn't feel the same.
China won 26 golds, just over half as many as it won in Beijing in 2008. Russian Federation - with its track team told to stay home because of the doping probe and a cloud hovering over its athletes who were in Rio - finished with 19 golds and 56 medals overall.
There were plenty of positives for others, however.
Bill Sweeney, British Olympic Association chief executive, said: "Though we are still deep in the middle of competing, one thing we know we will have had from start to finish and beyond is the incredible support of the Team GB fans, both in Rio and Great Britain and Northern Ireland".
