A significant proportion of items from a new range had been returned as faulty. When they investigated they realised a new factory they were using for this range had slipped a huge amount of bad items through the reatilers QA process. They ended up writing down the whole line and donating it to Oxfam/Redcross to be sold in their charity shops, very similar to Goodwill. It was 100,000's of items.
They were already writing the goods down as a loss against their balance sheet and they managed to recoup a small percentage of that loss as a tax deduction for the charity donation.
It didn't happen often, but it wasn't the first time they'd done it
ZA001 Went to Nagoya, Japan.
ZA002 Went to Pima Air and Space Museum (as you noted).
ZA003 Went to the Museum of Flight in Seattle.
As for the other three:
ZA004 may still be with Boeing.
ZA005 was scrapped.
ZA006 appears to have been sold to Mexico for a VIP transport.

Anecdata. I worked at a goodwill in the early 2000s for community service. A lot of people donate soiled rubbish disguised as clothing that goes to landfill. I would have no doubt that Goodwill has partnerships with department stores...or else they wouldn't have anything to sell.
This is what TJ Maxx/Marshalls used to do. The market is pretty diverse for this type of thing. There's a whole industry around it.
Looking at the chart, it appears these 3 brands were all in the top 4 most commonly sold (or at least available for sale) brands at Goodwill in by 2019, and they've been in the top 10 or so for years. I can't imagine organic amounts of resale from a Florida-only department store chain could account for this. So is Bealls just straight selling their old stock to Goodwill for cheap? Or maybe even giving it away as a write-off (and to reduce cost to store items they don't think they'll ever be able to sell). I wonder how much of Goodwill's stock actually comes from things like this, as opposed to houseful donations.
