President Donald Trump and his Democratic rival Joe Biden on Friday will both visit the crash site in the key election state of Pennsylvania of one of the planes hijacked during the September 11, 2001 terror attacks on the United States.
Both men will seek to take advantage of the solemn moment to appear as leaders seeking to heal a deeply divided nation.
For the 19th anniversary of the Al-Qaeda terror attacks, Biden -- who has recently stepped up his campaign after weeks of keeping a low profile due to the coronavirus pandemic -- will make two public appearances.
Friday morning, he will be in New York City for the annual event honoring the almost 3,000 people who died in the attacks on the World Trade Center.
Then he will travel to Shanksville, Pennsylvania, where an airliner crashed after the passengers tried to wrest control of the plane from the Al-Qaeda hijackers.
Biden is not expected to speak at the Ground Zero ceremony in Manhattan, an event traditionally reserved for families of the victims, who this year have pre-recorded their contributions.
His mere presence, however, will attract attention at an event that is broadcast live on the main US television networks and is punctuated by minutes of silence, the first one at 8:46 am (1246 GMT), the time that the first plane hit one of the Twin Towers.
Trump will be absent from the memorial in his native New York, but he will be represented by Vice President Mike Pence.
The Republican president could steal the show from Biden, as he will be at a commemoration in Shanksville, some 300 miles to the west of New York.
There is no chance of the two rivals crossing paths in Pennsylvania: Trump and his wife Melania are due to leave Shanksville in the morning after the memorial, while Biden and his wife Jill will not arrive at the site until the afternoon.

Neither of these appearances will feature any of the political showmanship according to Robert Shapiro, a political scientist at Columbia University. The 9/11 ceremonies are traditionally "free of rhetoric, dedicated to paying tribute to victims" of the attacks, he said.
The ceremonies will nevertheless be closely followed by the media, and offer Biden and Trump a chance to "show their leadership and empathy."
"There will be a temporary silencing of the more vitriolic rhetoric they are using against each other," Shapiro said.
The choice of both candidates to show up in Pennsylvania, an important state to win in the presidential election, illustrates the "obvious calculations" their advisors have made.
Long a Democratic stronghold and Biden's home state, Pennsylvania swung narrowly to Trump in the 2016 election, helping him secure his surprise victory over Democrat Hillary Clinton.
Polls show Trump and Biden nearly even in Pennsylvania, and Democrats hope to win the state back in the November 3 vote.
But if the somber commemorations mark a "truce," it is likely to be a short-lived one, as was the case in 2016.
Clinton took part in the New York memorial but left the event early because she was feeling ill. Her doctor later revealed he had diagnosed her two days earlier with pneumonia, which she had kept secret.
Trump leaped on the incident and for weeks mercilessly mocked his rival's health.
