Well eldon

Quite obviously the answer to that would be to gain knowledge, how do you think astronauts get into space. Im no pro but i imagine they practice first, i mean i would be slightly worried if my gas man turned up and said it was his first day, thats why Eldon why have PRACTICAL TESTS. Now my question to you why answear a question with a question? you must like wasting your own time i guess!

But thanks anyhow you have certainly opened my eyes, I REALLY SHOULD TRY TO BE MORE CLEAR OR MAYBE ASK THE QUESTION TWICE.
