Goes, well, like a rocket

Tonight's rocket launch:

From the video's description:

On September 30, 2011 at 11:08am, Derek Deville's Qu8k (pronounced "Quake") launched from the Black Rock Desert in Nevada to an altitude of 121,000' before returning safely to earth. Above 99% of the atmosphere, the sky turns black in the middle of the day and the curvature of the earth is clearly visible. The rocket motor produced 4,000 lbs of thrust for 8 seconds accelerating the vehicle to over Mach 3 at over 10,000'. After that, momentum carried the rocket skyward for another 84 seconds to a peak altitude of 121,000'.

Battle of the Rockets

Tonight's religious rocketry lesson:



According to this site, this event occurs on the Greek island of Chios during Easter:

The Rocket War of Vrondados is an old custom that began at the time of the Turkish occupation and it still happens every year at Easter. In the beginning the residents of the parishes of Panagia Erithiani and Saint Mark's, which are facing each other, made small cannons, to fire at each other. But through time the canons became rockets and fireworks made from nitre, sulphur and gunpowder.

The preparation of the rockets starts immediately after each Easter, so everything can be ready for the next year. Each year the amount of the rockets increases and the fireworks burning in the air, at the night of the Christ's resurrection, are really magnificent. Many people visit Chios Island this time of the year, so they can enjoy this truly unique but dangerous event. For this reason, the last few years measures are taken for the protection of all the people that participate in this event and the surrounding houses, so the custom can be continued safely.

Must be a tough job being a fireman during Easter on that island.
