My first post seems as good as any for some noobie fails. I started playing a couple days ago after watching Scott Manley's videos and thinking hmm this looks interesting, addicted now! xD Following his tutorials I haven't had any real problems so per se. My fails have been more noobie mistakes than forgetting things etc. Currently my most heartwrenching one, on my first attempt to send a craft to orbit the mun everything was going perfectly, got the craft there, orbited, sent it flying back to Kerbin. It all went wrong however due to a little impatience on my part I hit the atmosphere and would have come down 2-3 orbits later, thinking I was being clever I pointed my craft at what I thought was retrograde and fired the remaining 5 seconds or so of my fuel. Too late did I realise I'd fired prograde, 5 minutes and a blisteringly fast slingshot later I was now on an escape trajectory. Despite my best efforts I ended up in highly eliptical orbit around the sun, which despite my best efforts with Jeb's jetpack proved impossible to leave. I didn't want to leave Jeb to die alone in space so I tried to rescue him, but low level tech and inexperience with interplanetary encounters just led to 5 more stranded Kerbals. After a gruelling 50 years in orbit waiting for a favourable encounter with Kerbin (all the orbits of the sun passed within Kerbin's so I was hoping they would eventually get captured by it's SOI or at least slowed down to make rescue easier) Jeb just couldn't take it anymore and removed his helmet on a spacewalk, the other Kerbals quickly followed (I terminated the flights). On a lighter note, one of my other fails was not so bad! After getting into orbit and then running out of fuel and not being able to deorbit I panicked, but some 8 orbits and a bit of crafty jetpack pushing later I finally touched down!
