What was the Hindenburg?
At 800-feet long, the Hindenburg was the largest airship ever built--just slightly smaller than the Titanic. Also of a disastrous end, the zeppelin burst into flame as spectators watched it attempt to land in Lakehurst, New Jersey, on May 6, 1937. In under a minute, the Hindenburg was gone, people jumping from windows to escape. However, only 62 of the 97 crew members and passengers onboard survived. The exact cause of the disaster is still unknown and remains a historical mystery.

Peter Pritchard: general practitioner with “legendary” improvisation skills
Social conscience Peter had been born into an affluent family but his father's early death, combined with the effects of the Wall Street crash, meant that his mother had to bring up her young family in more straitened circumstances. In 1971, with colleagues, he ran the first training course for practice nurses, and in 1972 he helped to start the first patient participation group in the UK. In 1996, he helped to raise the money to buy the Hurst water meadow close to his home in Dorchester, and he served as the honorary secretary of the charitable trust until 2010, by which time he was 92.

HEAVY LIFT?
The company's prototype Airlander 10, a 302-foot-long, double-hulled craftthat can go 90 mph at 16,000 feet and carry 10,000 pounds of cargo, made news twice in August: first, for completing a 19-minute maiden test flight; and second, for ending a 100-minute flight with a nose-first \"heavy landing.\"

Thrust-Based Stabilization and Guidance for Airships without Thrust-Vectoring
The concept of thrust-based control without the employment of thrust-vectoring (TVC), already introduced in a previous work by the authors, is further developed in conjunction with an appropriate control suite, tasked with both artificial stabilization and beam-tracking navigation functions. In the paper, the fully non-linear mathematical model employed for testing the controllers in a virtual environment is outlined. Then a comparative approach is adopted in the analysis, where a standard tail-back airship with deflectable aerodynamic surfaces is employed as a baseline, and the performance of a four-thrusters layout with a thrust-based control and no TVC is assessed with respect to it. Featured test cases in forward flight include short climbs, abrupt turns, and multi-checkpoint navigation. The research supports the feasibility and adequate performance of the proposed thrust-based airship layout and control, and presents a critical analysis of the pros and cons with respect to the considered baseline airship configuration featuring standard aerodynamic control.

A comparative study of conventional and tri-lobed stratospheric airships
The design and development of Stratospheric Airships for High-Altitude Long-Endurance missions (HALESAs) has generated interest worldwide. Conventional airships usually have a single-lobed axisymmetrical envelope shape. In contrast, several non-axisymmetric envelope configurations have been proposed for the HALESAs, such as flattened single lobed and multi lobed. This paper describes a methodology for carrying out a comparative analysis of a conventional HALESA and the multi-lobed HALESA designed for the same design mission. A sizing methodology which enables the estimation of its design parameters to meet some user-specified requirements has been developed for airships with envelopes of both these shapes. A Multidisciplinary Design Optimisation (MDO) approach has been followed in this methodology, which includes considerations from the disciplines of aerodynamics, energy, environment and structures. The study indicates that the envelope volume, solar array area and total mass of the single-lobed conventional airship are better than those of the tri-lobed HALESA. While the multi-lobed HALESA has the advantage of a flatter upper surface resulting in higher efficiency of the solar panels, the conventional airship has lower drag, which results in superior mission performance.
