Hi Chris
The thing is, When Tighar go back an this is a big big IF. It is the Electra they will have to show the world the smoking gun, Which in turn will alert the gold diggers who have no conscience, An a piece of Amelia Earhart's lost plane i would imagine would go for more than what it would take to send Tighar back to see what the Anomaly is, Weather they retrieved it illegally or not in my opinion.
Thank's Richie
