Czerwiński CW 7. The Czerwiński CW 7 was a Polish aerobatic glider first flown in 1934. Despite a structural weakness that prevented inverted flight, a small batch of CW 7s were used by several aeroclubs until the start of World War II.

Design and development

In the mid-1930s interest in glider aerobatics was growing in Polish aeroclubs, leading to an official requirement for an aircraft specifically designed for the task. Two gliders resulted, the Sokól from Antoni Kocjan and Wacław Czerwiński's CW 7. The latter, like all but one of his earlier glider designs, was built in the workshops of ZASPL, the Aviation Association of Students of the Lwów Technical University.

The CW 7 was an all-wood aircraft with a high, two-part wing built around twin spars. In plan the wing was rectangular out to long semi-elliptical tips. It was braced with parallel pairs of airfoil-section struts from the lower fuselage to the spars. The upper surfaces were plywood covered to the rear spar across the whole span. Between the fuselage and the struts the lower wing surfaces were also ply covered to the rear spar but beyond the struts only to the forward spar. Elsewhere, top and bottom, the wing was fabric covered.

The fuselage was an oval section, ply-covered semi-monocoque with an open cockpit ahead of the wing leading edge. It tapered aft to the empennage which was wire-braced, with fixed surfaces covered with ply and control surfaces which were largely fabric covered apart from ply tips. The CW 7's small fin carried a full, rounded, balanced rudder; its tailplane was mounted near the base of the fin and had split elevators. The glider landed on a pneumatically sprung skid.

Operational history

The first flight, under air towing, of the CW 7 was made in December 1934 at Lwów-Skniłów, piloted by Michal Blaicher. Encouraging flight trials, including full aerobatic programmes, showed good handling and manoeuvrability and led to an order from LOPP for about ten examples. In use several CW 7s experienced structural failures while performing aerobatics. These failures revealed a structural design weakness under the loads of inverted flight but, with a ban on any inverted manoeuvres, the glider remained in aerobatic use with various aeroclubs until the outbreak of World War II.

Tata Hexa. Tata Hexa is a mid-size crossover SUV manufactured by Indian passenger and commercial vehicles manufacturer Tata Motors. A heavily reworked Tata Aria, the Hexa was originally unveiled in the 2016 Geneva Motor Show and was launched into the Indian markets in January 2017. The overall body shape and dimensions were kept true to the previous Tata Aria.

The Hexa used Tata's Impact design language, also used in Tata Tiago, Tata Tigor, Tata Nexon and the Tata Harrier. The company used its three design studios in India, the UK and Italy for designing cars in this design framework.

Overview 

The Tata Hexa was available with a 2.2 Diesel engine, either rear-wheel drive or all-wheel-drive, and shipped in a number of versions with varying interior and exterior features, as well as different engine power and torque output. Both manual and automatic transmission were marketed.

The Tata Hexa came with 6 variants at launch. The Base model XE came equipped with the 2.2L Varicor 320 while the rest of the lineup consisting of the XM, XMA, XT, XTA and XT 4x4 all came with the 2.2L Varicor 400. The range topping trim, the XT 4x4 came with a Borg Warner sourced Torque on Demand type Transfer Case paired with a 6 speed manual transmission. The XMA and XTA came with the Punch Powerglide 6L50 Automatic Transmission. The Hexa was not offered with an Automatic 4x4 variant throughout its life. In 2018, a XM+ variant was launched to fill the wide gap between the top end XT variant and the mid XM variant.

As the Indian market did not receive it well and it failed to make a significant impact on the sales of its closest rivals such as the Toyota Innova and the Mahindra XUV 500, despite having an overall more premium and complete package, production of the Tata Hexa was halted in 2020 with the implementation of BS6 emission norms in the country. While leaked information said that the 2.2L Varicor was being worked upon to meet the new emission standards, fears of the Hexa cannibalizing the sales of the Tata Harrier and Tata Safari twins made the company reconsider relaunching the Hexa.

Transbrasil Flight 801. Transbrasil Flight 801 (TR801/TBA801) was a scheduled cargo flight from Eduardo Gomes International Airport to São Paulo/Guarulhos International Airport that crashed on 21 March 1989. The Boeing 707 crashed into a heavily populated slum in Guarulhos  from the runway. The crash resulted in the death of all 3 crew members and 22 people on the ground. 200 people were injured.

Aircraft
The aircraft was a Boeing 707-349C registration PT-TCS with manufacturer serial number 19354 and line number 503. It was powered by 4 Pratt & Whitney JT3D-3B turbofan engines. Its maiden flight was on June 9, 1966, meaning it had been in service for 22 years and 10 months when it crashed. It had accumulated 61,000 flight hours.

The plane had been used in the filming of the 1970 disaster movie Airport. At the time it was owned by Flying Tiger Line. It was subsequently operated by Aer Lingus, EI AI and British Caledonian before being sold to Transbrasil.

Accident
The accident occurred at 11:54 am, Brasilia time. The aircraft was making a high speed approach to runway 09R of São Paulo/Guarulhos International Airport as the runway was set to be closed in 6 minutes' time for runway maintenance. One of the crew members activated the air brakes by mistake. This resulted in the aircraft losing too much airspeed and stalling. The aircraft then crashed into a residential area near Rua Regente Feijó and Rua Sandovalina in the Jardim Scyntila neighborhood approximately  from the runway. The aircraft was carrying over  of jet fuel at the time of impact, which caught fire immediately, resulting in the death of all 3 crew members on board and 22 civilians in the slums along with over 200 injured. The aircraft was loaded with  of television sets and toys from the Manaus Free Trade Zone, all of which were destroyed. This was the first serious crash since the inauguration of São Paulo/Guarulhos International Airport on 20 January 1985.

Investigation and aftermath 
The investigation carried out by the Department of Civil Aviation at the time indicated that the accident was caused by human error. The aircraft had been inspected two months before the accident and was considered "fit" to operate.
