It's now been one year since a UPS plane crashed in Louisville, leaving 15 people dead.

Yesterday, people gathered for a memorial service at the site of the crash, and at least one survivor says he still wants answers and accountability for what he calls a preventable tragedy.

Our June Leffler has more.

Louisville and public officials gathered this week to honor the 15 people killed from the crash, and those who responded to the distressing scene.

Our skies covered in an inky black shroud, apocalyptic ash falling as far away as on the high school sports fields in Saint Matthew's.

People calling, standing outside, looking up, wondering what had happened.

During unimaginable challenges.

You always want to ask the why?

Why here?

Why Louisville?

Why do these things have to happen at all?

We're left with so many unknowns, so much pain and so much loss.

Time itself does.

Not restore a business, a livelihood, or a sense of normalcy.

Survivors are still hurting.

Businesses are still rebuilding.

Victims families and friends are still learning how to carry grief.

That may change with time, but will never fully go away.

The crash happened nearest to an auto parts and recycling company.

Workers and customers on site at that time were killed, along with three UPS pilots.

The company's owner read their names.

Lives taken needlessly far too soon.

John Boyd, Megan.

Allen.

Trina.

Ella.

Angela.

Matthew.

John, Tony, Carlos and his beautiful three year old granddaughter Kimberly, along with three pilots Captain Richard Wattenberg, Captain Dana Diamond, First Officer Lee Truitt.

And he is still looking for answers.

This was avoidable without those responsible taking accountability.

It leaves an open wound that does not heal.

It tells us those responsible believe corporate greed is more important than human life being directly to UPS, which is what flight 2976 had painted on it on behalf of those impacted in the entire community.

Simply speak as a staple and economic engine for this community.

Be a good corporate citizen and stop hiding behind a hollow, canned statement and tell the committee, the community your position on this avoidable tragic accident.

UPS says it cannot speak freely on this matter because it's still under investigation.

The National Transportation Safety Board, or NTSB, is the federal agency conducting the ongoing investigation.

The agency was on site shortly after the crash.

It released a preliminary report last year stating mechanical issues with the plane.

It also held a multi-day hearing this year, but has yet to release a final report on what went wrong or what safety measures need to happen to prevent similar catastrophes.

And my hope is that in the near future that everyone feels that things have been made as right as they can, knowing that nothing can replace those who we lost.

The investigation right now is the federal authorities are doing the entire investigation.

My understanding is that they'll have a final report in the springtime, and my hope is that that provides more answers than we have today.

Victims families have filed lawsuits against UPS, Boeing and two other companies that build or fix parts for the type of cargo plane that crashed.

For Kentucky edition, I'm June Leffler.

UPS held its memorial yesterday as well, alongside firefighters who responded to the scene.

The company says it offered financial and mental health support in the wake of the crash, and that it is committed to continued recovery efforts in Louisville.

Today, a reporter asked Governor Andy Beshear if he was satisfied with how UPS has handled the aftermath of last year's crash.

Here's the governor's response.

I would like to see it all resolved as quickly as it can be.

I know that these types of situations result in the type of lawsuits that are ongoing right now.

Up certainly has a right to defend itself in those lawsuits, but I would like to see us not have this not play out for years, to make sure that we can come to resolution, that those families are appropriately compensated and that they can move on with their lives.

So I don't want to be overly critical of of UPS, because I don't know what those negotiations are, and they are an absolute critical employer here in Kentucky.
