Sword plant gone terrestrial

I don't always get a chance to check on my tanks during the week if work is
crazy. Yes, the fish get fed and their basic needs (water :-) ) looked
after.

So I go down to the basement today to do my weekly water change(s) and see
one of my Sword plants climbing out of the tank. It was about 14" above the
rim of the tank. It didn't have any leaves on it yet, just a massive stock
with four leaf buds. The stock was about 1/2" at the base. I've read about
Swords being grown above the water in green houses, but now I can see why.
The amount of growth in one week was phenomenal.
