If you are looking for signs of "real progress", call the company and ask them when the next mini-evacuation is scheduled for. They will tell you, as I myself confirmed that this morning. There is also a large amount of optimism that the problems uncovered in past minis have been resolved, and that this next mini-evacuation test should go very well.

Their phone number can be found on their website, but I will post it here for simplicity: 718 244 8880
