russians at lake vostok not lost

US News reports failure to respond doesn't mean Russians lost or even in trouble.  Russians are working around clock to reach goal to drill into ancient Lake Vostok before winter closes down operation, believes American explorer John Priscu. A perturbed Priscu discounts recent Fox report Russians at Lake Vostok lost, because of no reported contact for five days. "'I never said the Russians were lost,'" comments Priscu.  The world will hinge on Russian find, although any account, may be months away?
