I came across this engine, which is used in the Celera 500L, but is also offered for other applications (I've seen a DHC Beaver and a crop duster): It's a 6.1 l V12, twin turbo diesel engine. Rated at 550 or 600 shp. View: https://www.youtube.com/watch?v=y2WZJJ5IzMU

This is an alternative history of Goddard's historical liquid rocket launch of 1926 and the succeeding development of a fictional experimental rocket airplane based on Goddard's designs. The advent of the design and its governmental support ultimately leads to a change in the course of the US...

I recently visited the United States Army Aviation Museum at Fort Rucker, AL, and I came across the McDonnell Douglas Mark II Batwing. I haven't been able to find any information on this aircraft other than what was on the Museum's sign, and the only evidence of its existence on the internet is...

Registered as N22C in 1949 and cancelled in 1955. has anybody got any info?

A more theoretical question than alternative history, was there any interest within SAC to develop a "Heavy" ICBM to match the R-36's capabilities? If so, could it fit within the existing Titan II launch sites? Titan II and R-36 are somewhat surprisingly similar in diameter and height, though...

I haven't made a post on here in ages but today I stumbled upon something very strange and interesting only the people here might know of to find. I was going on a romp around Japan in Google Maps looking at aviation museums and such and I came across a museum near Nagoya Airport owned by...

In the late 1950s the US deployed a bewildering range of tactical nuclear weapons in Western Europe. The US Army had its spectacular 280mm atomic cannon mounted between two trucks. It then had smaller 8" warheads for the M115 howitzer which were made available to the UK and other NATO allies...

About 6 months ago I came across mention of a Havoc variant known as the Havoc Pandora, or Havoc III It was built upon RAF Havoc Is but featured a 2000ft cable with an aerial mine attached. 20 units were converted and used by No.240 Flight (redesignated No.93 Sqn). Eventually they were converted...

http://www.hisutton.com/Lockheed-Stealth-Submarine-Design.html Neat little article i found, I'm curious how much it would have effected things if it had been built, al lest one as a prototype.

Long before the Welbike, the American inventor Arthur Hugo Cecil Gibson in 1915 during the First World War, offered his motor vehicle to the American army. A 22.5 kg combat scooter that can carry a load of 136 kg at a speed of 40 km/h but was not accepted however it did not differ so much from...

Hai Except some drawings concerning the P-33 projects, I did not find any information concerning other Brewster projects. The only which I earlier mentioned was the two-seat fighter, further no details etc. Is there any material/information concerning this two-seat fighter and other not...
