I managed to find some news on this subject via google search:
8/19/2011. Our Voyage to Our Hollow Earth expedition under the leadership of Steve Currey was cancelled upon his death in July 2006 and all monies returned to expedition members. However, expedition members expressed the desire to continue the quest. Physicist Dr. Brooks Agnew offered to become our new expedition leader and the Currey expedition members voted "Yes" to that offer. Dr. Brooks Agnew subsequently renamed the expedition the North Pole Inner Earth Expedition, and has been working ever since to raise the money to fund it. Of the 100 possible seats on the Russian nuclear icebreaker that is hoped to be chartered, 20 seats are reserved for former expedition members. The rest Dr. Agnew wants to take are scientists and other technical people to record in detail any discoveries made. Since these nuclear icebreakers will be decommissioned at the end of next year 2012, and the reservation fee of $700,000 must be paid by December of this year, 2011, if this expedition is to happen, donations must come into Dr. Agnew's Phoenix Science Foundation enough to cover the cost. To apply to be part of the expedition, go here, and then visit the North Pole Inner Earth Expedition website here. Since there are so few seats on these nuclear icebreakers, and so many that have applied to go, I am suggesting an alternative route to our hollow earth.Source: http://www.ourhollowearth.com/ourhollo/p3.html
Is this the expedition you were talking about?
I also found an interesting article which presents a brief summary of
Hollow Earth Theory. http://mitchtestone.blogspot.com/2011/0 ... art-i.html
It's a fascinating topic, though I'm not convinced. Need to see some harder
evidence. That's why an expedition would be very useful, even if it's just to
rule out the theory. Having said that, I'm not closed minded. I do accept that it's
possible, but I'm yet to be persuaded.
