Golden Nugget blackjack is a mixed bag. Its Bonus Spin Blackjack in the front party pit is the worst blackjack game in Las Vegas. If you walk past that pit, you will find $15 six-deck blackjack games that pay 3:2. Double down before and after splitting, as well as surrender, are offered. Hillsborough County is a county located in the west central portion of the U.S. State of Florida.In the 2010 census, the population was 1,229,226, making it the fourth-most populous county in Florida and the most populous county outside the Miami metropolitan area.A 2019 estimate has the population of Hillsborough County at 1,471,968 people, which itself is greater than the populations of 12. Another potential downside is Stadium Blackjack pays 6-to-5, rather than 3-to-2. Then again, that’s true of the majority of blackjack games on the Las Vegas Strip. Also, serious blackjack players dislike six deck, continuous shuffling machines. Card counting is impossible with such machines.

Version 1

Version 1 of 21+3 I noticed at the Las Vegas Hilton in April, 2001. The side bet pays based on the player's first two cards and the dealer's up card. If the three cards equal a flush, straight, straight flush, or three of a kind the side bet pays 9 to 1. The following table shows the probability of each hand in a six-deck game,as played at the Hilton.

The Caesars Entertainment Blog mentions that the xtreme version of 21+3 can be found in the Party Pit at the Paris casino in Las Vegas. I had to chuckle at their sense of humor with this remark,

'We would calculate the odds of hitting these side bets, but being in Vegas isn't about math, it's about having fun. And just never-you-mind that this is the blog of a casino company. Check out the new Ooh La La Party Pit at Paris Las Vegas the next time you’re in the neighborhood.

Hey, it is about the math everywhere, even in the Party Pit!

Top 3 Blackjack

Air Test and Evaluation Squadron TWO ONE (HX-21) 'Blackjack' is a U.S. Navy aircraft squadron located at Naval Air Station Patuxent River, Maryland on the Chesapeake Bay. As part of the Naval Air Warfare Center Aircraft Division (NAWC-AD), Naval Test Wing Atlantic (NTWL), HX-21 is responsible for the Developmental Test and Evaluation of Navy and Marine Corps rotary-wing/tilt-rotor aircraft, airborne systems, and Unmanned Aircraft Systems (UAS) in support of acquisition decisions that improve the Navy and Marine Corps' war fighting capability. Additionally, HX-21 tests and evaluates new mission systems to integrate legacy aircraft into the constantly evolving fighting force.

History of TWO ONE[edit]

On 1 April 1949, the United States Navy formally established a rotary wing flight test section under Flight Test Order No. 2-49 whereby all tests and trials of rotary wing aircraft and associated equipment would be conducted under a rotary wing section of the Naval Air Test Center's flight test division. This rotary wing section was responsible for the scheduling of tests and development of criteria for reporting the test results for rotary wing aircraft types. This designation was maintained until April 4, 1975 when rotary test and evaluation was established as its own separate aircraft test directorate known as the 'Rotary Wing Aircraft Test Directorate' (RWATD). RWATD was then redesignated into the Rotary Wing [aircraft] Test Squadron (RWaTS) on July 21, 1995. RWaTS finally became Air Test and Evaluation Squadron TWO ONE on May 1, 2002 to better align with fleet squadron naming conventions.

History of the Patch[edit]

Legend has it the original Rotary Wing Aircraft Test Directorate patch (right) was designed on the kitchen table of the first Technical Director, Richard 'Dick' Wernecke, and has remained in place to this day.

HX-21 Original Patch

Since that time, OPNAVINST 5030.4F has come into effect, changing the specifications governing squadron patches, requiring HX-21 to redesign the current insignia. The redesigned patch is symbolic in many ways and shares similarities with the original. The genesis of the new design is as follows:

Crossed Rotor Blades: The crossed blades are found in the original design and are a classic reference to helicopter flight test. The red center portion of the rotor headpreserves the 'T' in Rotary Wing, depicted above in the original design.
Blackjack: The Blackjack is a heraldic symbol used to illustrate the squadrons’ designation of 21, or the winning hand. The 3-D image of the Blackjack grabbing the Ace is symbolic of the Test Teams taking control of the situation.

Sword: The sword shown represents the strength, courage and determination required to make the tough decisions and stand one's ground when challenged.

Color and Pattern: The patch is predominantly black due to the blackjack call sign, while adding red, yellow and white rounds out the colors of the Maryland State flag.

Overview[edit]

Air Test and Evaluation Squadron TWO ONE (HX-21) performs developmental testing and evaluation of all Navy, Marine Corps and Coast Guard rotary wing/tilt-rotor aircraft, Unmanned Aerial Vehicles (UAVs) and associated sensor and weapons systems. A wide range of aircraft testing and support is provided to include flying qualities, aircraft performance and aeromechanics, shipboard suitability, tactical aircraft mission systems testing, ordnance compatibility, ballistics, system reliability and maintainability assessments, flight simulator/simulation fidelity, and aircraft software development. Support is also provided to a variety of industry and international developmental efforts to include shipboard envelope development and expansion, day and night electro-optical capabilities, and flight test technique improvements.

Composition[edit]

HX-21 Test Pilot Requirements[edit]

Blackjack

Blackjack +3 Game

To become a test pilot, one must be a seasoned operational pilot who is selected for and completes a military Test Pilot School such as the United States Naval Test Pilot School (USNTPS), a highly selective school for the best qualified fleet pilots and flight officers from every branch of military service, as well as civilian engineers. Students learn new flight test techniques, how to draft and publish test reports and how to conduct special test and evaluation projects on various types of aircraft to include fixed-winged, rotary-wing, and tilt-rotor aircraft, in addition to UAVs. Pilots selected for assignment at HX-21 must be qualified, highly trained, and possess a wide range of operational experience in rotary and/or tilt-rotor aircraft.

Former test pilots make up a high percentage of astronauts and HX-21 has been home to some notable figures, including Suni Williams, a former helicopter test pilot at HX-21, who went on to become a NASA astronaut. She was assigned to the International Space Station and was a member of Expedition 14 and Expedition 15. Suni Williams holds the record for the longest space flight for any female (195 days). Another figure is Mr. Richard 'Dick' Wernecke. Mr. Wernecke served the Naval Air Test Center for 34 years as a project engineer, a Department Chief Engineer, and as the first Technical Director of the Rotary Wing Aircraft Test Directorate from 1975–1988.
