Main Engine.

They're smaller than I had expected.

All 3 parts are awesome. You are really lucky to be ablet o see some of the last shuttle operations close up like this. Cool

I was not expecting the engines to be that small either. I mean, they're still fairly big but for the amount of kick they give, they're pretty small. The bulk of them is in the nozzle. There's a whole lot of parts for such a 'simple' reaction to get that shuttle in the air (and out of it)

Great shots.

An extraordinary piece of engineering that simple looking engine is. Grin

All held together with a piece of string! Cheesy

Seriously ... great shots - you're one lucky guy.

Did they mention that with the vertical doors open on the VAB you can slide the United Nations Building right in? (If you have a mind to!)

That's a great thing to remind people when they say that the shuttle is a huge polluter. Instead of making nasty and harmful gases that will destroy the atmosphere, the liquid fuels produce the key thing vital to our survival Wink

(SRBs are a different matter though)
