Discussing the time @Zoë O'Connell and I were talking our boat, Scarlet, into Shoreham harbour when I saw light glint through a thin nylon thread in the air in front of me.
“Fishing line!” I yelled, more out of instinct as it posed no threat to us, surrounded, as we were, by the stainless steel rigging lines of our boat.
The line made contact with the starboard shroud. This did … very little to our 8000 kilogram metres per second of momentum. The line turned into a delicate gossamer spiral in front of us as it instantly broke.
The fisherman on the harbour wall high above us started jumping up and down, yelling.
Like, you cast your line across the entrance to a working harbour…
…in front of an approaching boat…
…which can’t see your line…
…and even if it did, cannot manoeuvre out of the way or stop in time even if it wanted to.
So, congratulations, I gu

So, congratulations, I guess. You “caught” a whopper: 4 tonnes! Shame you couldn’t reel it in. Go tell your friends about the one that got away.
Some people are just a bit thick, I guess.

Unknown parent • • •@alastair One of my favourite facts about the Shuttle is the Return to Launch Site abort mode. Literally “spin ‘er around and blast back to base”.
The Shuttle would spin around, with the external tank still attached, and execute a burn until it has nullified its down range velocity and can start to head back to Kennedy Space Center. It would then jettison the ET and try to land.

in reply to Katie Fenn • • •@alastair There was once a plan to test this abort scenario for real, but the astronaut office vetoed it. They thought it was so dangerous it wasn’t worth testing even once.
This is how the Shuttle stack ended up being tested, “in production”, on STS-1.
The astronauts would rather fly an untested stack than try the ridiculously risky abort mode.

in reply to Sarah Brown • • •@alastair Apollo 12 was also struck by lightning, which wiped out the guidance and the telemetry. A single flight controller was able to figure out what had happened, and instructed the crew to flip a single switch that saved the mission.
If they hadn’t have fixed it, they would’ve had to abort.
