THEY came on a September morning, literally out of the blue.

The apocalypse arrived on four planes, hijacked by Islamist terrorists who then flew them into the World Trade Center, the Pentagon, and a field, after attempting to destroy Camp David.

It was an attack on America but its repercussions affected the entire world.

It was a moment that nobody will ever forget, including these Daily Echo readers:

Angie Seagrave

I was at home in England with my toddler son, news flash came up on TV screen so I turned the TV over to see what the major event was and saw the 2nd plane go into the tower live on TV.

I couldn’t believe what I was seeing then,still cant 20 years on.

RIP to all those innocent people that went out to work, run errands and meet friends that day and never came home.

Daily Echo:

Carolyn Chandler

My husband and me were in Malta on holiday – one I will never forget!

I was worried about my brother who used to fly every day for his job.

Took two days to find out if he was okay.

Lisa Fozzie

We were on our honeymoon in Bali, we heard mutterings around the pool and the atmosphere just changed.

Then we saw what was happening on the TV.

It was so surreal we couldn’t believe that it was real at first.

So shocking and sad.

Daily Echo:

Julie McDonald

At home watching tv when a newsflash came up just as the second plane went into tower.

Stood in silence.

Remember going to pick my son up from school and nobody was talking just getting there kids and heading home.

Watched it for rest of day and night with my son praying for all the people that had been lost and for all those missing.

Its a day that will never be forgotten.

Donna Marie Stansbridge

My daughter was 10 and her dad and I had taken her to Disneyland in America.

We were evacuated from the grounds as they feared other attacks.

They issued us tickets to return that have no end date.

One day we hope to return with the grandchildren.

Ness Brown

I was just getting ready to go to collect my girls from primary school and had the TV on, couldn’t believe my eyes.

Remember getting to school and saying to school gate Mum’s that things were never going to be the same again.

Barry M Biddiss

Driving back home from London when I heard it on the radio.

It had to be the the day I will never forget in my life.

God bless all the people that lost their lives that day and lots of love to all the families that lost their love ones.

Stewart Wilkinson

Was on break from lecturing and saw TV in common room!

Thought it was a movie like war of worlds?

Only later found out the true horror.

How can anyone be so inhuman?

RIP all who died. A blessing on all who assisted.

Jonny Vandijk

I was 14 at the time.

I finished school early as I had a dentist appointment and got to my friend’s house just after the first tower was hit.

I remember just standing in silence staring at the television just trying to take in what was actually occurring and praying for the safety of everyone affected.

Daily Echo:

Rebecca Jane

Was heavily pregnant with my second child, and was in Blackpool at the time, when I saw it on the news.

I was an emotional wreck and couldn’t wait to be back home with my eldest child and hold her and not let go.

Aimée Brander

I was 11, off school sick and just flipping through the channels on TV, when I saw the second plane hit.

I didn’t fully understand what had happened but I was scared and ran into the garden to tell my mum and my neighbour what I’d seen.

I’ll never forget how everyone reacted. We were so far removed in the UK but it was terrifying to watch.

Daily Echo:

Sarah McDonald

Working at the Daily Echo I went to lunch & whilst driving back I heard a news flash on the radio but couldn’t really understand what was happening.

When I walked back into the office everyone was gathered around the TV screens in editorial watching events unfold.

Sandra Shirley Connell

I was working in a hospital where the consultant I worked for as his secretary was overwhelmed with emotion by the news as his fiancee was working in that area.

She survived and eventually came to England.

In the porters room the TV was left on all day for us to check the news.

Shock and disbelief was experienced but the more we watched the news we knew for certain it was true.

Still a mind boggling frenzy of thoughts occupied people’s minds and then the realisation a family member or friend could be injured or even dead.

I witnessed the man who is usually well composed crumble in front of me.

Thankfully his fiancee returned to England following these events.

It was a very sad time.

Daily Echo:

Bex J Gransden

I was 13, stood in my school uniform watching the second plane hit the building live on tv.

There was utter silence in my house from the complete shock of what we were watching.

The next few days after, the whole community was in disbelief.

I was terrified of every plane flying overhead after that!

Dawn Welland

Out fly fishing with my late husband.

The trees were autumn colours and beautiful, then home to the horrors of what was happening.

Daily Echo:

Pam Brierley

I was at bingo and when we were leaving the TV was on and I saw what I thought was a film.

How terrible it was to see.

My sympathies are with everyone who has been affected.

Julie Killick

Just had my first child and remember being sat in the hospital bed at the princess Anne and sat in utter shock at what was being seen on the news.

Remember holding my daughter with midwives stood by the bed watching the TV.

I was thinking what type of world have I just brought this baby into and being scared of what else was to come.

I remember it all so well.

The most memorable time of my life – becoming a mother but so scared by what I was watching.

Allie Bunyan

Watching Neighbours on tv when the news came on showing live pictures. Saw the second plane hit the tower live. Couldn’t believe what I was watching.
