Alliance Takes the Hill
Monday, April 19 – Thursday, April 22, 2021
Entertainment, Receptions, Classes, Seminar, Booth Shows, and a March on Capitol Hill
Join the Alliance as we take our fight to the Hill in 2021! As business owners and technicians, you deal with a lot of obstacles in your day-to-day operations. Politics don't help. Our industry faces a lot of threats: drivers rights to their vehicle's data, your ability to access that data to make repairs, tariffs, and more. The time for sitting on the sidelines is over. It is time for us to take a stand and be heard. We look forward to seeing you in Washington, D.C. as we rally together for Auto Value and Bumper to Bumper!
The Alliance will host receptions, dinners, workshops, and evenings full of entertainment and giveaways that you won't want to miss at the Gaylord National Resort & Convention Center in National Harbor, a nationally-recognized waterfront destination. Standing on the shores of the Potomac River, this stylish resort offers convenient access to many of the prime D.C. destinations which are bound to be on your bucket list. This resort features an 18-story glass atrium overlooking the river and the city, while a full-service spa and seven distinct restaurants offer plenty to choose from at the hotel. We hope you'll join us in taking a stand and influencing decision makers at the most unique convention in Alliance history.

The RTV-G-4 Bumper was a sounding rocket built by the United States. A combination of the German V-2 rocket and the WAC Corporal sounding rocket, it was used to study problems pertaining to two-stage high-speed rockets. https://iokxhg.over-blog.com/2021/01/windows-excel-formulas.html. The Bumper program launched eight rockets between May 13, 1948, to July 29, 1950.[1] The first six flights were conducted at the White Sands Missile Range, the seventh launch, Bumper 8 on July 24, 1950, was the first rocket launched from Cape Canaveral.[2]

Bumper program[edit]
The Bumper program was conceived in July 1946 by Colonel Holger N. Download microsoft access crack. Skynet 2020 terminator. Toftoy.[3] It was started on June 20, 1947, to:
- Investigate launching techniques for a two-stage missile and separation of the two stages at high velocity.
- Conduct limited investigation of high-speed high-altitude phenomena.
- Attain record-setting velocities and altitudes.

Overall responsibility for the Bumper program was given to the General Electric Company and was included in the Hermes project. The Jet Propulsion Laboratory was assigned to perform the theoretical investigations required, design the second stage, and create the basic design of the separation system. The Douglas Aircraft Company was assigned to fabricate the second stage, and do detailed design and fabrication of the special V-2 rocket parts required.
Six Bumper launches, as well as other V-2 test launches, were from White Sands Proving Grounds. In 1949, the Joint Long Range Proving Ground was established at Cape Canaveral Air Force Station on the east coast of Florida. The July 24, 1950, Bumper 8 launch was the first of hundreds of launches from 'the Cape'.[2]
