In today’s travel industry the import keyword in bookings is PNR Status . PNR stands for personal name record or passenger name record. In the complete details of the passenger and his or her trip details will be stored in the database of a Computer Reservation System (CRS) company such as Sabre, Galileo, Worldspan and Amadeus which will be updated for every minute through online. More over most of the people in India and other countries of the world are interested in make online reservation to make the travel smoother and faster. So PNR Status made the reservation process into simple task so that people who book their tickets can check their status of booking. Coming to railways sectors which is one of the fastest growing industries in the present of the world. While coming to the railway reservations done by allotting a unique PNR Status. This PNR which stores the details of the passenger and his or her trip details which is a computerised record which is updated for every minute th...

In the late-1950s, many of the surplus Boeing B-17 Flying Fortresses that were used by the Navy, Air Force, and Coast Guard in the air-sea rescue role found their way into the hands of several civilian fire bomber operations that for the first time along with surplus Consolidated PB4Y-2 Privateers, offered a quantum leap in performance with the ability to carry significant loads of fire retardant. In fact, prior to the arrival of the B-17s and PB4Y-2s, no other civilian fire bomber then in use even remotely approached the fire retardant capacity of the converted four-engined bombers. In 1960, the first of about two dozen B-17s were converted with bomb bay tanks for aerial delivery of fire retardants. The bomb bays were fitted with tanks that could carry 2,000 lbs of retardant. The tank was then subdivided into four compartments, each compartment having its own quick-opening door to empty that tank on a forest fire target. The converted B-17s were based on the -F and -G variants prim...

In 1969 homebuilt aircraft builder and boat designer George Pereira of Sacramento, California, started work on the Osprey I homebuilt flying boat. Using his technical background in powerboat design and construction, Pereira designed the Osprey I as a high-performance STOL sea plane intended for the growing homebuilt aircraft market. With folding wings, a single-seat open cockpit and able to be transported by a boat trailer, the Osprey I was made of wood, fiberglass, and styrofoam with a Continental C90 four-cylinder 90-hp piston engine mounted on a dorsal pylon driving a fixed-pitch two-bladed propeller. With one pilot and a full load of fuel, the aircraft weighed only 900 lbs and had a top speed of 135 mph. After finishing the design and construction, Pereira had to demonstrate that the Osprey I could safely be flown during an FAA mandatory 50-flight hour restricted flying period to be completed in less than six months. Having duly met the FAA's requirements for a kitbuilt airc...

The Convair Model 6, I have to jump back a bit and talk about both the XC-99 and the YB-60 as they're both derivatives of the B-36 Peacemaker. Convair's work on the B-36 began in the midst of the Second World War as there was a concern that Great Britain would fall to the Reich and we would need strategic bombers that could reach Europe from the United States. But in parallel to the development of the B-36 there were design efforts that looked at passenger versions of the B-36. As early as May 1942 Convair had been looking at a transport version of the B-36 called the Model 37 that combined the wing, six pusher piston engines and empennage of the B-36 to a new fuselage unit. In December 1942 the USAAF signed a contract with Convair to build a single example of what was designated the XC-99 on the stipulation that the XC-99 would not divert resources from the B-36 project. Convair saw the XC-99 as a way to validate some of the design concepts of the B-36 quickly as it would no...

To boost morale on the home front during the Second World War, aircraft manufacturers celebrated production aircraft milestones. Lockheed, for example, painted the 5,000th P-38 Lightning red and named it "YIPEE". But Boeing wanted to do something different as it approached the 5,000 B-17 Flying Fortress to be built since the attack on Pearl Harbor when the US entered the war against the Axis. Aircraft number 40-37716, a B-17G, was that aircraft and early on it was marked with a notice on the fuselage that it was the 5,000th Flying Fortress to be built since the US entry into the war. Every worker who played a part in the construction of this particular aircraft was invited to sign the aircraft as it advanced down the production line in Seattle. It celebrated the efforts of the thousands of workers who emigrated to Seattle to escape the effects of the Great Depression and work on Boeing's massive production facilities. The enthusiasm that workers applied their signatur...
