It is not the first time the Duke of Cambridge has gotten involved with mental health charities.
Meanwhile, William - who has Prince George, five, Princess Charlotte, three, and Prince Louis, four months, with his wife Duchess Catherine - announced in January 2017 that he would be stepping down from the job and said it was a "huge privilege" to work with the East Anglia Air Ambulance.
While there, the man got candid about his own experience working as an air ambulance pilot and how that affected him mentally.

The Duke of Cambridge, on Tuesday, attended the launch of a new project called Mental Health at Work, set up by two charities namely: Heads Together - which Prince William co-founded with his wife Catherine and Prince Harry - and Mind Charity.
"You're always dealing with despair and sadness and injury".
"As employers, we have a real opportunity to change the way we approach mental health, giving our people the support they need to thrive".
The Mental Health at Work initiative is available online which it is hoped will benefit small to medium companies who struggle to find the help.More news: FDA mulls ban on flavored e-cigarettes
A total of 44,000 workers were questioned as part of the survey by Mind and only half of those who had experienced poor mental health said they had talked to their employer about the issue.
Mind surveyed more than 44,000 employees and found that nearly half had experienced a mental health problem at their current job - and only half of this 48 per cent had talked to their employer about it.
Farmer added on the dedication that not just Prince William, but all the Royals, have to mental health awareness: "My firm belief is that all of [the royals] and particularly the Duke - in this context - have done a lot of background work and really thought about this issue and their commitment is 100 per cent real".
