And then my chance really happened in 1996 when we added the second flight of the tether satellite.

And the first flight of the tether satellite happened in '92, and I was the backup on that flight.

I started this whole endeavor really. And at the beginning we had the selection in Italy. And that was pretty much among people that had held previous experience in that particular satellite. So, I was in that, in a good position then.

When this space walk will be completed, then the arm will be fully operational and ready for the next activity that will be pretty much the testing, the first flight testing of the space station arm.

And just when we were at the end of our design process there was the news that the Italian government and the U.S. government had signed an agreement to fly the first Italian astronaut on that flight.

And so, I will be probably, since I am not involved in all the activity, I will have some spare time to devote to document all this busy part of the flight.
