What we've said in the past is that we look at this as an investment. We didn't have any specific plans for making a bid, but there was just a lot of speculation out there.

What we are doing is selling an investment that has been a very good one for us. It's up threefold since we initially started buying stock.

I wouldn't rule out further investments within those categories.

Aviation is notoriously cyclical....it's a question of capital allocation and not having all our eggs in the same basket.

Everything we pour into the shuttle is an investment in the past.

Our productivity growth has not been that great over the past few years. Now we've got this investment appetite and that could really start moving us up productivity-wise. The downside is you don't need as many jobs in the sector as you did before.
