White Knight II & Spaceship II - Revell 1/144 ( built by Bianca Krop-Kaiser )

The Scaled Composites Model 339 SpaceShipTwo (SS2) is a suborbital, air-launched spaceplane designed for space tourism. It is under development as part of the Tier 1b program under contract to The Spaceship Company, a California-based company that is wholly owned by its sister company Virgin Galactic. The Spaceship Company was formerly a joint venture between Virgin Galactic and Scaled Composites, but Virgin became the company's sole owner in 2012.
SpaceShipTwo is carried to its launch altitude by a jet-powered mothership, the Scaled Composites White Knight Two, before being released to fly on into the upper atmosphere, powered by a rocket motor. It then glides back to Earth and performs a conventional runway landing. The spaceship was officially unveiled to the public on 7 December 2009 at the Mojave Air and Space Port in California. On 29 April 2013, after nearly three years of unpowered testing, the spacecraft successfully performed its first powered test flight.
Virgin Galactic plans to operate a fleet of five SpaceShipTwo spaceplanes in a private passenger-carrying service, starting in 2014, and have been taking bookings for some time, with a suborbital flight carrying an initial ticket price of US$200,000.[ The spaceplane could also be used to carry scientific payloads for NASA and other organisations.

 The duration of the flights will be approximately 2.5 hours, though only a few minutes of that will be in space. The price will initially be $200,000. More than 65,000 would-be space tourists applied for the first batch of 100 tickets. By December 2007, Virgin Galactic had 200 paid-up customers on its books for the early flights, and 95% were passing the 6-8 g centrifuge tests. By the start of 2011, that number had increased to over 400 paid customers, and to 575 by early 2013. In April 2013, Virgin Galactic announced that the price for a seat would increase 25 percent to $250,000 before the middle of May 2013, and would remain at $250,000 "until the first 1,000 people have traveled, so that it matches up with inflation since [Virgin Galactic] started."
Following 50–100 test flights, the first paying customers are expected to fly aboard the craft in 2014. Refining the projected schedule in late 2009, Virgin Galactic declined to announce a firm timetable for commercial flights, but did reiterate that initial flights would take place from Spaceport America. Operational roll-out will be based on a "safety-driven schedule". In addition to making suborbital passenger launches, Virgin Galactic will market SpaceShipTwo for suborbital space science missions.

To many, the London Blitz is an integral part of the image of World War II. However, the Blitz lasted only for two periods, not the entire war. The first was between August 1940 and May 1941. The second was the era of the flying bomb.

The V-1, also known as a 'doodlebug', was an early example of what is today known as a cruise missile. The first V-1 strike on London was on June 13, 1944, although the rockets were invented some time earlier. Bomb strikes on the launch sites kept them from being effective until mobile launchers were invented. This strike took out the railway bridge on Grove Road. Many watchers initially mistook the V-1 for a plane and the fire of its rocket engine for signs that the plane was hit.
The truth was that the age of the unmanned aerial attack had arrived. With about 190 being fired in every day, the doodlebugs flew both day and night. Previous Blitz raids had taken place only at night, when the British fighters found it harder to eliminate the German bombers. The expendable V-1s changed all of that. The sound of the V-1's engines was compared to a motorcycle that would shut off fifteen seconds before the impact. Because they could be heard coming, they had value as a terror weapon. In fact, over a million people fled London as a direct result of the doodlebug raids. Some V-1 warheads caused devastation over a 600 yard radius, although the average was closer to 400.
It is estimated that over 14,000 people were killed by doodlebugs. Far more were injured and the property damage was almost immeasurable. For example, on June 30, Aldwych was hit, immediately outside the Air Ministry. The blast walls partially held, channeling the energy of the blast down the street and mowing down pedestrians. Fifty people were killed. In September 1944, the V-1 was replaced by the V-2, the world's first ballistic missile.
The physical and psychological impact of the doodlebug attacks was considerable. The effect on civilian morale was far greater than that of the plane-based attacks of the earlier Blitz. Despite this, many people did choose to remain in London and face the attacks. Both the garden Anderson and in-house Morrison shelters proved to be remarkably effective against the V-1s. Tube station shelters, which had also seen use in the early part of the Blitz, were re-opened, and new deep shelters built along the line of the Northern Line. The last V-1 to land on English soil landed at Swanscombe, Kent on March 28 1945, less than two months before V-E day.
Despite its effect on civilian morale and the large amount of damage done, the V-1s did not help Hitler win the war. indeed, they seem to have had very little impact on the end result. However, they were an unforgettable and traumatic experience for many Londoners, and also set the stage for much of modern air warfare.
