the last thing i'd do if a cop was writing me out a ticket was to try and push him out the way with my car and try and drive off, the driver is an obvious idiot..

the cop has every right to stand in the way, its upto the driver to wait for him to move, if he doesnt then you dont go trying to push him out the way..

driver is an obvious ass and im happy he got put to the ground
 
Another build of my own design.
After a few doodles and working on a wing planform that has been floating around in my head for a while now I came up with this:

I'm sure it's pretty obvious where I got the idea for the wing shape from. Birds of prey and many seabirds (actually most birds) have this shape to their wings. In no way does this imply that anything with this wingshape is going to fly well, in fact through many tests aircraft designers have come to the conclusion that it's more due to the need to be able to get their wings out of the way when they're not flying that birds have evolved into having bent wings. The best fliers out there, like the wandering albatross, have very long straight wings but I have always been taken by the classic bird of prey shape.

So the first step was to build a small throw plane to test the concept. To my great surprise it flew really well. Actually I shouldn't have been surprised, as they say, if you have the right COG and enough power, a toaster will fly. Thankfully my idea wasn't at all toaster shaped so power wasn't too much of an issue!

That evening I got to building and I applied some rules (not for any other reason than aesthetics) derived from photography. Namely the rules of thirds. The rules of thirds suggests that the most effective and attractive photos typically have the image split into thirds either horizontally or vertically (over simplified but this is the gist of it). I decided to leave the rudder for now and went with a bank and yank configuration with two servos on the wings so that I could at a later stage experiment with flaperons.

So I give you - The Kestrel

It flies really well once the CG is sorted and has a surprisingly benign stall characteristic. It will basically pancake from the stall and float all the way down. It flies really well fast or slow and is capable of pretty decent roll rates and loops.

At the end of the day, the officer was stood in front of the car on the drivers side at around the 14 second mark. Regardless of whether or not he put his foot under the wheel after that, the driver still tried to drive forward in to the officer.

ANYWAY

I present to you the Tsar Bomba:


From Wiki:
It was so powerful that the shockwave reflected the fireball back in to the air & was ~8km in diameter & was seen nearly 1,000km away. The subsequent mushroom cloud was about 64 kilometres (40 mi) high (over seven times the height of Mount Everest), which meant that the cloud was above the stratosphere and well inside the mesosphere when it peaked. The base of the cloud was 40 kilometres (25 mi) wide. All buildings in the village of Severny (both wooden and brick), located 55 kilometres (34 mi) from ground zero within the Sukhoy Nos test range, were completely destroyed. In districts hundreds of kilometres from ground zero, wooden houses were destroyed, stone ones lost their roofs, windows and doors; and radio communications were interrupted for almost one hour. One participant in the test saw a bright flash through dark goggles and felt the effects of a thermal pulse even at a distance of 270 kilometres (170 mi). The heat from the explosion could have caused third-degree burns 100 km (62 mi) away from ground zero. A shock wave was observed in the air at Dikson settlement 700 kilometres (430 mi) away; windowpanes were partially broken to distances of 900 kilometres (560 mi). Atmospheric focusing caused blast damage at even greater distances, breaking windows in Norway and Finland. The seismic shock created by the detonation was measurable even on its third passage around the Earth. Its seismic body wave magnitude was about 5 to 5.25. The energy yield was around 7.1 on the Richter scale but, since the bomb was detonated in air rather than underground, most of the energy was not converted to seismic waves. The TNT equivalent of the 50 Mt test could be represented by a cube of TNT 312 metres on a side, approximately the height of the Eiffel Tower.

Takes a while to get going, but starts properly in the late 50s.

I'm amazed California still exists after the US has spent the last 60 years blowing the crap out of it.
 
Yeah, that's a great piece of work.

It amuses me that Britain joins the game and immediately starts blowing up Australia :p
 
and there was me thinking that hardly any nukes had gone off since the second world war. i guess 99% of them were for testing purposes, but i had no idea there were that many

What ever happened to the 1963 test ban treaty?

Edit: and they missed a trick there. They should have punctuated each explosion with the "ding" sound from DEFCON.
