Sanjay Van. Sanjay Van is a sprawling city forest area near Vasant Kunj and Mehrauli in Delhi, India. It is spread over an area of 443 acres. It is one of the most thickly wooded areas of the city’s green lungs.

Concerns
The forest, which is part of the Mehrauli South Central Ridge, has undergone severe degradation in recent times with the proliferation of the Prosopis juliflora tree which is non-endemic to the Aravalli Ranges and has caused depletion of the ground water level, killing native flora and changing the natural soil characteristics of the Aravallis. Sewage water and effluent which is discharged into Sanjay Van has also affected this green belt in the Capital.

Restoration Work
Amid a growing demand from nature lovers, the forest is going to be made a bird sanctuary. The Sanjay Van, which is presently undergoing restoration through a unique collaborative effort between the Delhi Development Authority and a citizen's group, may well serve as a model that will be replicated to restore other ridges in the capital.

Attractions

Apart from heritage, the area is one of the few recluses for bird watchers and nature enthusiasts. Resident or visiting birds include the Indian peafowl, grey heron, Eurasian golden oriole, purple sunbird, Asian koel, Brahminy starling, Indian silverbill, grey-breasted prinia, crested honey buzzard, white-throated kingfisher, rufous treepie, Indian paradise flycatcher, Eurasian sparrowhawk, red-wattled lapwing, cattle egret, common moorhen, white-breasted waterhen, grey francolin and the Jacobin cuckoo, a migrant from Africa that breeds in this forest.

The forest also conserves natural habitat for the nilgai, golden jackal, snakes and a large variety of butterflies.

Terrain
As the land is a part of Aravalli Range it shows all the characteristics of the same. Some areas have flat lands some have uphills and downhills. The whole area is full of big giant rocks forming a small hill every here and there. It has got some small drains spreading all over the areas which can be seen in every 300-400 meters of a walk. Overall we can say it has got a terrain of forest and hills.

Visit
There are multiple entry and exit points, but the ones at the Qutub Institutional Area and Neela Hauz Bridge near Vasant Kunj provide the easiest access and least confusion. Visitors are advised to wear shoes and full-length trousers as protection against the thorny shrubbery, and to take sufficient fluids and snacks, as there is no kiosk or shop in the quiet of the woods.

ATOL 495. Atol is a two-seat kit amphibious aircraft with a wood composite structure. It was to be built in ultralight and light-sport aircraft (LSA) versions. Atol aircraft were produced by the Finnish company Atol Avion.

In April 2017, it was announced that the aircraft would be built for the North American market by Atol USA of Brunswick Landing, Maine.

By 2022, the company website had been taken down and the domain was for sale.

Development 
The Atol was designed by Markku Koivurova and produced by Martekno Ky and later Atol Avion Ltd. The development of Atol began in the 1970s, inspired by the American Osprey II. The first versions of the design used the Ken Rand KR structure. Atol's predecessors were larger and their structure recalled the traditional structure of a wooden aircraft.

The first water taxi tests of the new LSA version, the Atol 650, were commenced in December 2014 on the Kemijoki River, Finland, on the Arctic Circle. This new version first flew on 9 April 2015.

The 650 model was intended to be built in Maine, United States, with European deliveries initially forecast for late in 2018 and US deliveries starting in 2019.

On 3 July 2018, the 650 LSA prototype (OH-XNA) crashed and burnt, near Rovaniemi.

By November 2022, the company website had been taken down, and the domain was for sale. It is likely all development on the aircraft has ended. The proposed American manufacturer, Atol USA, was administratively dissolved on 13 August 2021.

JetGo. JetGo was an Australian regional airline and air charter company based at Eagle Farm, Queensland near Brisbane Airport.

It operated scheduled domestic passenger services in the Eastern states of Australia and charter services, particularly fly-in fly-out (FIFO) operations in support of the mining and resources sectors.

Overview

JetGo took delivery of its first 37-seat Embraer 135 aircraft in March 2012. and was granted an air operator's certificate by the Civil Aviation Safety Authority (CASA) in May that year. As of July 2012, JetGo was operating FIFO and charter services throughout Australia. Despite having a business model initially focused on charter operations, following approval by CASA in October 2014, JetGo announced it would begin establishing regular public transport services. The company planned to grow its fleet to as many as 10 aircraft, focusing on longer regional routes in Queensland and New South Wales of between .

JetGo announced two original routes from Sydney to Roma and Tamworth, both scheduled to commence in November 2014. After delaying the start of Sydney-Roma route however, the airline announced that the services would not proceed. In February 2015, Jetgo also announced that it would suspend its Sydney-Gladstone service, citing poor patronage.

Shortly after announcing its inaugural routes, JetGo announced that it would operate services between Brisbane and Tamworth, with up to 10 flights per week. The launch of the route was timed to coincide with the annual country music festival in January 2015.

On 1 June 2018, the airline was placed under voluntary administration, and all scheduled passenger operations were suspended. The Supreme Court of New South Wales ruled that JetGo to be liquidated, following the creditors report by the administrators that showed it owed $38 million to creditors and may have been trading while insolvent since 30 June 2016.

Gerald H. Rosen. Gerald Harris Rosen (born August 10, 1933, Mt. Vernon, New York) is an American mathematical scientist with over 280 published contributions in leading international scientific journals from 1958 to the present, in the areas of theoretical physics, mathematical biology, and aeronautical engineering.  Rosen is currently the M. R. Wehr Professor Emeritus at Drexel University, in Philadelphia, Pennsylvania, United States.

Education 
At Mt. Vernon's High School, he earned varsity letters in track and football as a sprinter.  He graduated first in the Class of 1951.  Subsequently, at Princeton University, he majored in Engineering-Physics, winning the Sophomore Math Contest (1953), the Whiton Engineering-Physics Scholarship (1953), the Guggenheim Jet Propulsion Scholarship (1954), the Alton Prize (1955), and a 3-year National Science Foundation Pre-doctoral Fellowship (1955).  He graduated first in the Class of 1955 of 729 students.

At Princeton University, Rosen received the degrees B.S.E. in 1955, M.A. in 1956, and PhD in 1959.

Career 
Rosen was an NSF postdoctoral fellow in 1959 at the Institute for Theoretical Physics in Stockholm, Sweden, returning to the United States in 1960 to serve as a consultant to the Joint Chiefs of Staff.  In 1962, as principal scientist at Martin-Marietta, he derived an equation, which is now known as Electrodynamic Tether (OML Theory).  OML Theory has been independently rediscovered by other mathematical physicists more than 30 years later.  Between 1963 and 1966, he did research at the Southwest Research Institute in San Antonio, Texas.   Among the important research papers composed during this period was:  "Particle-like Solutions to Nonlinear Scalar Wave Theories", Journal of Math. Phys., Vol. 6, p. 1269 (1965), which has been resurrected recently by Russian theoreticians;  see publication 32 at Gerald Rosen's website.

In 1966, he accepted a tenured full professorship at Drexel University in Philadelphia where he is currently on the research faculty in Physics as the M. R. Wehr Professor Emeritus.  His most important recent works pertain to the masses of leptons and quarks  (pubs. 270 and 272), and to dark energy and matter (pubs. 273 and 274).

Electric Aircraft Corporation ElectraFlyer-C. The Electric Aircraft Corporation ElectraFlyer-C is an American experimental electric aircraft that was designed by Randall Fishman and produced by his company Electric Aircraft Corporation in 2008. The aircraft is a converted Monnett Moni motor glider intended to test electric propulsion technology for the future Electric Aircraft Corporation ElectraFlyer-X.

The design was only intended as a prototype and proof of concept aircraft.

Design and development
The aircraft features a cantilever low-wing, a single-seat enclosed cockpit with a bubble canopy, fixed conventional landing gear and a single  electric motor in tractor configuration. The sole example built is registered in the US Experimental - Amateur-built category.

Constructed from a Monnett Moni motorglider with  taildragger landing gear, the original fuselage and wing were retained, but the tail section and tailwheel were extended to improve control on the ground, and to elevate the fuselage.

The aircraft is made from sheet aluminum. Its  span wing has an area of .

The motor is an 18-horsepower ElectraFlyer direct-drive propulsion kit DC electric motor, powered by a pair of custom-made 5.6 kwh lithium-ion polymer battery packs, weighing 75 pounds (34 kilograms). The batteries are mounted in custom-made, ceramic-stainless steel firewall boxes, sized to fit the space available in the fuselage.

The motor returns an 88% efficiency (90% at cruise), with the motor controller consuming 2% of the power. The batteries fitted give an endurance of 1.5 hours and take six hours to recharge at a cost of 70 cents for the power consumed. While descending the propeller generates power to recharge the batteries. The ElectraFlyer-C received its airworthiness certificate on 11 April 2008.

Fishman indicated that he would sell the aircraft in April 2009, but as of February 2017 it remains owned by his company.

Craft of Opportunity Program. The Craft of Opportunity Program (COOP) was a Royal Australian Navy (RAN) acquisition program intended to supplement the navy's mine warfare capability with civilian vessels that could be quickly converted into minesweepers. Vessels acquired under COOP were not commissioned into the RAN, and instead operated with the prefix "MSA" (Minesweeper Auxiliary).

Acquisitions
COOP was initiated in 1985, to cover the gap in mine warfare capability caused by the decommissioning of the Ton-class minesweepers and delays in building their replacements, the Bay-class minehunting catamarans. In order to equip the auxiliary vessels, the RAN acquired several Klein Type 590 towed sidescan sonar arrays, along with Mini-Dyad magnetic influence sweep arrays, AMASS influence sweep arrays, and mechanical minesweeping gear. When the Bays were found to be poorly suited for minehunting work, the COOP vessels were kept on until the Huon class entered service, with some retained even later as a supplementary force.

Six vessels were purchased under COOP:  and  (ex tuna fishing boats),  (a lighthouse tender), , and the Bandicoot-class minesweepers Bandicoot and Wallaroo (former Singaporean harbour tugboats). Another three trawlers, Salvatore V, Waverider, and Carole S, were chartered. Also acquired under the program were three drone ships, which could be operated from the auxiliary minesweepers. Although not directly a part of COOP, the Defence Maritime Services training ship Seahorse Horizon can also be fitted out as an auxiliary minesweeper.

End of the program

By 2012, most of the vessels have been sold or returned to their owners. Bandicoot and Wallaroo have not been operated as minesweepers since 2010, but were retained until 2014 to provide berthing support for nuclear-powered warships. The drones have been non-operational since 2007, and are due to be replaced by 2013.
