The cross of Lorraine is also used in the SABRE GDS ( global distribution system ), a computer program used by travel agents.

Travel agencies also use the services of the major computer reservations systems companies, also known as Global Distribution Systems ( GDS ), including: SABRE, Amadeus CRS, Galileo CRS and Worldspan, which is a subsidiary of Travelport, allowing them to book and sell airline tickets, hotels, car rentals and other travel related services.

SABRE ( Synergistic Air-Breathing Rocket Engine ) is a concept under development by Reaction Engines Limited for a hypersonic precooled hybrid air breathing rocket engine.

Alan Bond says that the technology readiness level of the SABRE engine is, as of May 2009, 2-3.

Like the RB545, the SABRE design is neither a conventional rocket engine nor jet engine, but a Precooled Hybrid Air Breathing Rocket Engine that burns liquid hydrogen fuel combined with an oxidant of either compressor-fed gaseous air or stored liquid oxygen fed using a turbopump.

The successful experiment means that this technology is likely to be incorporated into the final SABRE design.

The designed thrust / weight ratio of SABRE ends is high — up to 14 — compared to about 5 for conventional jet engines, and just 2 for scramjets.

The precooler is also the most aggressive and difficult part of the whole SABRE design.

Started in 1999, the Society for All British and Irish Road Enthusiasts ( SABRE ), originally known as " Study and Appreciation of the British Roads Experience ", is one of the larger and most prominent communities of road enthusiasts online.

Although SABRE is primarily an online group, members organize group tours to visit sites of interest.

* The A64 ( M ) portion of Leeds Inner Ring Road is classified as a " pathetic motorway " by one SABRE member because it is " sadly, only 800 yards long and that's if you go the long way.

It is interesting to compare the system with SABRE, being deployed at about the same time by American Airlines.

Equally interesting is that while the SABRE CPU was about ten times faster, ReserVec handled 80-100, 000 transactions a day with a maximum two second delay, while SABRE handled only 26, 000 with delays of up to three seconds.

The RB545's precooler had issues with embrittlement, relatively high liquid hydrogen consumption, patents and Official Secrets Act, so Bond went on to develop SABRE in its place.

Unusually the combustion chambers in the SABRE engine are to be cooled by the oxidant ( air / liquid oxygen ) rather than by liquid hydrogen to further reduce the systems overuse of liquid hydrogen compared to stoichiometric.

In addition, unlike the LACE concept that preceded it, SABRE ’ s precooler does not liquefy the air letting it run more efficiently.

The central core of SABRE behind the precooler uses a turbo-compressor run off the same gaseous helium loop Brayton cycle which compresses the air and feeds it into four high pressure combined cycle rocket engine combustion chambers.

Instead, using a gaseous helium coolant loop, SABRE dramatically cools the air from 1000 ° C down to-140 ° C in a heat exchanger while avoiding liquefaction of the air or blockage from freezing water vapour.

In contrast, the SABRE engine permits a much slower, shallower climb, air breathing and using wings to support the vehicle, giving far lower fuel usage before lighting the rockets to do the orbital insertion.

The lead engineer from the HOTOL project has since set up a private company dedicated to creating a similar plane called Skylon with a different combined cycle rocket / turbine precooled jet engine called SABRE.

A hybrid jet like SABRE needs only reach low hypersonic speeds inside the lower atmosphere before engaging its closed cycle mode, whilst climbing, to build speed.

An engine derived from the SABRE concept called Scimitar has been designed for the company ’ s A2 hypersonic passenger jet proposal for the European Union-funded LAPCAT study.

The outcome of this thinking was obvious from the start ; in 1971 the Air Force started a " requirements development " combining the ICBM-X and SABRE concepts into a single platform, " Missile, Experimental ", or MX.

SABRE was first started as an experimental effort in 1953, and a formal development contract signed in 1957.

* A pair of 7090s in Briarcliff Manor, NY, were the basis for the original version of the SABRE airlines reservation system introduced by American Airlines in 1962.

In spite of official disinterest, during the late 1960s Kenneth Fertig managed to arrange some funding through the Air Force for the " SABRE " project, short for " Self-Aligning, Boost and RE-entry " INS.

The unusual status of the A6144 ( M ) had led to its gaining a number of fans, particularly within organisations such as the Society for All British And Irish Road Enthusiasts ( SABRE ).

By the 1960s, with the American Airlines SABRE reservations system up and running, IBM offered its expertise to other airlines, and soon developed Deltamatic for Delta Air Lines on the IBM 7074, and PANAMAC for Pan American World Airways using an IBM 7080.

Membership was seeded by searching AA's SABRE computer reservations system for recurring phone numbers.

In particular, the IBA's E & D Department developed SABRE ( Steerable Adaptable Broadcast Receiving Equipment ) that enabled mainland broadcast television channels to be received for re-broadcasting in the Channel Islands.

Before the introduction of SABRE, the airline's system for booking flights was entirely manual, having developed from the techniques originally developed at its Little Rock, Arkansas reservations center in the 1920s.

With SABRE up and running, IBM offered its expertise to other airlines, and soon developed Deltamatic for Delta Air Lines on the IBM 7074, and PANAMAC for Pan American World Airways using an IBM 7080.

This product suffered from stiff competition from IBM's SABRE system in the US, but there was nothing similar in the UK, whose own airlines were in the market for such a system.
