The above is a direct copy of the Wikipedia page. On another site, I found this: It had a tail with 3 vertical stabilizers enabling use of existing hangars and to provide sufficient fin-area to maintain flight on only 2 engines running at one side. Ceiling on only 2 engines was 2440m. There is a large amount of additional data on this website: https://www.aircraftinvestigation.info/airplanes/Douglas_DC-4E.html

The Douglas DC-4E was an American experimental airliner that was developed before World War II. The DC-4E never entered production due to being superseded by an entirely new design, the Douglas DC-4/C-54, which proved very successful. Many of the aircraft's innovative design features found their way into the Nakajima G5N bomber after the single DC-4E prototype was sold to a Japanese airline and clandestinely dismantled for study by Nakajima at the behest of the Imperial Japanese Navy. The design originated in 1935 from a requirement by United Air Lines. The goal was to develop a much larger and more sophisticated replacement for the DC-3 before the first DC-3 had even flown. Such was the initial interest from other airlines, that American Airlines, Eastern Air Lines, Pan American Airways and Transcontinental and Western Air (TWA) joined United, providing $100,000 each toward the cost of developing the new aircraft. As cost and complexity rose, Pan American and TWA withdrew their funds in favor of the Boeing 307 Stratoliner, which was anticipated to be less costly. With a planned day capacity of 42 passengers (13 rows of two or more seats and a central aisle) or 30 as a sleeper transport (like the DST), the DC-4 (as it was then known) would seat twice as many people as the DC-3 and would be the first large aircraft with a nosewheel. Other innovations included auxiliary power units, power-boosted flight controls, alternating current electrical system and air conditioning. Cabin pressurization was also planned for production aircraft. The novel tail with three low vertical stabilizers enabled use of existing hangars and provided sufficient vertical fin area to allow the aircraft to take off with only two engines on one side operating. The wing planform was similar to the DC-3, with a swept leading edge and almost straight trailing edge. The four 1,450 hp (1,080 kW) Pratt & Whitney R-2180-A Twin Hornet 14-cylinder radials were all mounted with noticeable toe-out, particularly the outer pair.

The de Havilland DH.92 Dolphin was a 1930s British prototype light biplane airliner designed and built by the de Havilland aircraft company. The Dolphin was designed as a modernised version of the de Havilland Dragon Rapide, incorporating ideas from the company's DH 86A and de Havilland Dragonfly but using new main assembly designs. It had a DH 86A-style nose to accommodate two crew side by side and increased span wings of unequal span, Dragonfly-like. It first appeared with the trousered undercarriage of these earlier biplane transports, but a retractable landing gear, rather like that of the DH.88 Comet was fitted before flight. Onboard air-stairs were one of the passenger access novelties. It was powered by two 204 hp (152 kW) de Havilland Gipsy Six piston engines. Fuel tanks were in the wings, as in the Dragonfly, to avoid the fire hazard of the Rapide's engine nacelle tanks. One prototype was built and first flown on 9 September 1936. Geoffrey de Havilland's log shows that he flew it only once more. No others were built as it proved to be too heavy structurally and the prototype was scrapped in December 1936. The only photo of the Dolphin on the internet.

No, this is a freeze frame from a video of the flyby. I couldn't get a link to post. Comments on the video said they were throwing the C-17 around like a fighter.

Interesting photo showing decompression cloud on a C-17 left wing only, the right wing clear.

According to airport-data.com, this Avid Flyer was built in 1995. https://airport-data.com/aircraft/photo/000802937

Popping a door in a Bonanza is similar - cold and loud. Did it once doing solo touch and goes at Moorabbin back in the 70's. Made it a full stop, closed and latched the door, back to the holding point and off again. The door sat about 3 inches ajar during the landing.

The only report is behind a newspaper paywall. Covered on both 7 and 9 news.

The plane was a Jabiru 120. The pilot sustained a broken elbow.

The Croses EC-9 Para-Cargo is a 1960s French six-seat tandem-wing cargo-carrying homebuilt aircraft designed by Emilien Croses. Developed from the earlier two-seat EC-6 Criquet and three-seat EC-8 Tourisme, the Para-Cargo was a cargo-carrying aircraft with a tailwheel landing gear and a tandem wing similar to the Mignet Pou-du-Ciel family. It could carry up to six persons or 450 kg (990 lb) of freight and was intended especially for carrying skydivers: the aircraft was equipped with a large side door that hinged inward and upward to facilitate skydiver egress. Another door at the rear of the fuselage was provided to allow oversize loads to be carried. The Para-Cargo aircraft had Cosandey Flaps, rear wing mounted upward deflecting flaps that can be used independently to assist in roll control, or jointly as an elevator, that were often mistaken for ailerons . At least two examples (F-ACVC and F-PYBC) had been built by 1965. At least 2 units were built.
