Post-Sudan exploration program was TLM's quicksand event.
Once in quicksand, the more you struggle, the faster you sink. If you don't do anything, you'll eventually sink.
TLM just threw off a big packsack to reduce weight.....that will slow down the sinking. But someone might have come along in a few minutes that could have grabbed onto the packsack and pulled TLM in.
And that packsack was real nice, too......
