Paumier MP2 Baladin
The Paumier MP2 Baladin is a rare French light sporting aircraft developed in the late 1950s and early 1960s as an advanced amateur-built design by Maurice Paumier, an aviation enthusiast and designer. The prototype was constructed over four years by members of the Aero Club de Courbevoie near Paris, reflecting the era's emphasis on homebuilt aircraft for recreational flying. It achieved its first flight in early 1961, showcasing innovative features for a small two-seater, including a clean aerodynamic profile that contributed to its impressive performance relative to its powerplant.[1][2] The aircraft employs a single-engine, two-seat side-by-side configuration in a low-wing monoplane layout, optimized for sporting and touring roles. Its wooden structure is primarily covered in plywood for strength and smoothness, with fabric applied to the wing undersurface aft of the front spar, ailerons, and the aft fuselage to reduce weight while maintaining durability. Key features include a variable-pitch Flottorp two-blade propeller, electrically actuated split landing flaps for improved low-speed handling, and a retractable tricycle undercarriage with a steerable nosewheel sourced from motor scooter components for simplicity and cost-effectiveness. Fuel tanks are integrated into the wing leading edges, accessible via orifices at the wingtips. The powerplant is a four-cylinder, air-cooled, horizontally opposed Continental C90 engine producing 67 kW (90 hp), providing reliable performance for its lightweight frame.[1] Specifications| Parameter | Value |

Safewing MP II Flight
Safewing MP II Flight is a propylene glycol-based Type II de-icing and anti-icing fluid developed by Clariant for aviation ground operations, designed to remove ice and snow from aircraft surfaces through high-pressure spraying of heated fluid.[4][5] The fluid can be applied hot or cold, either neat or diluted, and is compatible with standard spray equipment, ensuring effective coverage during winter conditions.[4] It provides protection against refreezing by offering holdover times as specified in FAA guidelines, which vary by weather conditions and fluid concentration; for example, under freezing fog at -3°C and above with 100/0 dilution, holdover times range from 3:30 to 4:00 hours, while for light snow in the same conditions, times are 1:35 to 2:35 hours, and for moderate snow, 1:00 to 1:35 hours.[6] These times are fluid-specific and exceed generic Type II benchmarks, with the lowest operational use temperature (LOUT) at -29°C, allowing application in a wide range of cold environments but not below this limit.[6] Key features include a low surfactant content for reduced foaming and environmental impact, full biodegradability of its additive package, and a triazole-free corrosion inhibitor that enhances aircraft material protection without toxic residues.[4] In practice, it is typically used in diluted mixtures such as 75/25 or 50/50 for initial de-icing to shear off contaminants, followed by neat (100%) application for anti-icing to form a protective film.[7] This process complies with SAE AMS 1428 for performance and ISO 11075 for quality standards, ensuring reliability in global airport operations.[4][8] Introduced around 2014 as an eco-friendly option, Safewing MP II Flight has become widely adopted for its superior environmental profile compared to earlier glycol-based fluids, supporting sustainable practices in aircraft maintenance.[4][9]Firearms
Uzi (MP2)
The Uzi is an open-bolt, blowback-operated submachine gun designed by Israeli military officer Uziel Gal in the late 1940s and early 1950s, with production beginning in 1954 by Israel Military Industries (IMI).[10] Intended primarily for paratroopers and close-quarters combat, its innovative design featured a telescoping bolt and a pistol grip-integrated magazine well, allowing for compact size and rapid reloading while maintaining reliability in harsh conditions.[11] The weapon fires the 9×19mm Parabellum cartridge and uses detachable box magazines of 25, 32, or 40 rounds, with variants such as the compact Mini Uzi introduced in the 1980s for even greater portability.[12] In the German Bundeswehr, the Uzi was adopted in 1959 as the Maschinenpistole 2 (MP2), with the fixed-stock version designated MP2 and the folding-stock model as MP2A1, serving as a replacement for earlier submachine guns like the MP38/40 in secondary roles.[13] Initial orders totaled over 100,000 units by the mid-1960s, produced under license with some components sourced from FN Herstal, and it became a standard personal defense weapon for tank crews, artillery units, special forces, and infantry support personnel due to its simplicity, low maintenance needs, and effectiveness in confined spaces.[13] The MP2 remained in widespread service for nearly five decades, contributing to operations and training across NATO exercises, before being gradually phased out starting around 2006 in favor of the more advanced Heckler & Koch MP7 personal defense weapon.[14] Key specifications of the standard MP2 include:| Feature | Specification |
