Everyone hopes that part or all of Charlie Papa's remains will be found this weekend or soon after, but we have to continue to be realistic. The BEA is interestingly vague about the deadline of Phase 4.
"The search could last up to 100 days..."
"... this operation... will last 16 weeks [112 days]..."
"The operation... is designed to cover the search area in 4 months [~122 days]."
Fingers crossed it doesn't come to that.
