Cygnus CRS3 launch failure

That's abit different- they don't know where and on whom it will land. PLus they don't sound half as bothered IMO.
Far mroe dangerous too, Us launched rockets carry self destructs ( which happened yesterday), Russian rockets dont, if they go off track better not be where they land...I assume the engines are designed to go over 100% to make up for shortfalls in other engines - happend to the shuttle (see recent thread where one fault made up for another fault and the shuttle survived that launch).

Do you understand the magnitude of a shockwave caused by an explosion like that?

Nope. Engines end up being rated for over 100% due to improvements in the thrust capability over time, and not wanting to rewrite or change previous procedures. So, an engine that previously was rated at say 100KN and gets re-engineered to be capable of 110KN will be referred to as running at 110%. If the new higher thrust was called "100%" there is a danger than any previous thrust level could also be increased accidentally.Eric Mc said:

YesThey need to hand their man cards in.
There was a substantial bunker built for Apollo, IF they could get to it in time. The Saturn V had a bit of potential...... not quite this small but still....

And this popped up in the search, some cool 360 images

For me, closest has been a grenade in the next room. Biggest impact was a 500lb bomb approx 250m away. Largest being 2000lb+ from approx 1km.
The 500lb was so intense the whole vehicle I was on top of tipped to one side and I honestly thought I had been hit.
I can see some going into shock but full on crying, no, that needs a man up. Guessing they take cover when someone slams a door.

Remember how many people blubbed and wailed when Diana died... we live in strange times.The 500lb was so intense the whole vehicle I was on top of tipped to one side and I honestly thought I had been hit.

You'd have thought that considering the energy release potential in case of a malfunction, that launch facilities might be somewhat designed / armoured to prevent excessive damage in such cases? Perhaps it's cheaper to just rebuild it after an accidental low level bang? (and i guess you get a "Free" facility upgrade, or at least a nice new coat of paint, too??)Max_Torque said:
