No money in it, but sometimes you do things despite there not being any money in it. Besides, how often do you get a chance to help like this? It's pretty cool (if you ignore that it's only possible because a man's life is in danger).
Here's the email Amazon sent out to their mturkers:
Subject: Help find Steve Fossett, missing aviator
Greetings from Amazon Mechanical Turk,
On Monday, September 3, 2007, Steve Fossett, the first person to fly a plane around the world without refueling and the first person to fly around the world in a balloon went missing in Nevada. An airplane he was flying failed to return. No one has any idea where he is. Click on the following link for the Wikipedia article: http://en.wikipedia.org/wiki/Steve_Fossett.
Through the generous efforts of individuals at several organizations, detailed satellite imagery has been made available for his last known whereabouts.
HITs have been created to ask volunteers to help review these images and flag potential areas of interest which will be instrumental in the search and rescue efforts. If you are interested in helping, please click on the following link to participate in the search effort: http://www.mturk.com/mturk/searchbar?requesterId=A1U5V688O4PR3V
This is a race against time and any help you can provide will make a huge difference.
Friends and family of Steve Fossett would like to thank you for helping them with this cause.
