It is 55 years to the day since eight United players and three of the club's staff were among 23 killed when a flight from Belgrade crashed on the runway after a refuelling stop in Germany.
Sir Matt Busby famously rebuilt his side, and a decade later United became the first team from England to win the European Cup.
And Giggs - the most decorated player in the club's history - says every new arrival at Old Trafford is taught about the importance of the tragedy.
He told the United website: "New players, especially the foreign players, are joining a club which they think is great and offers them everything that comes from United being successful over the last 10 to 15 years.
"We all watched a DVD about Munich recently. It was really important for the squad to watch that and learn about what happened.
"Not only about the crash itself but also the success they had before it and how the team moved forward in the aftermath, from winning the next game to winning the European Cup 10 years later. Everyone was moved.
"I think it's very important, to know how the Busby Babes played and how successful they were before the air disaster and to know how Sir Matt built another great team.
"There are so many things that are relevant to us today and we need to carry on their legacy."
