NASA studying unexpected performance of Orion’s heat shield ahead of crew mission

[smp]

From Ars Technica:
"..."During inspections there were more variations across the heat shield than we expected," said Howard Hu, the Orion program manager for NASA. "Some of the charred material ablated away differently than what our computer models, and what our ground testing, predicted. More of this charred material was liberated during reentry than we had expected."..."

Yet another Euphemism to add to the Aerospace Industry Lexicon:

"Unpredicted Liberated Material"

Goes right up there with Space-X's "Rapid Unscheduled Disassembly"
