airplane

What would be the effects of Miami becoming a major airline destination, instead of merely a gateway to Latin American airports (such as those in Cuba or the Bahamas)?

What if instead of the Zeppelin becoming the common form of public air transportation, the Jet Airliner became the commonly used? What if the experimental Jet Airliner design and engine was perfected, and instead became the air transportation that the public use, instead of the Zeppelin?

What if the first wide-body airliner split classes a different way? What if wide-body airliners split different classes of passengers left and right of the twin aisles? When Boeing introduced the first wide-body airliner, they were the first airliners with two aisles. What if first class...

I'm wondering it it's possible for the airplane to be invented in the 19th century, and what would change if it did get invented then.

The rigid airship (commonly referred to as the Zeppelin) is what many people think of when they think of air travel. The big, silver whales of the sky, after many iterations and improvements throughout its 119 years of existence, carry over 4.5 million people every single day! However, it was...

WI no one invents the radial engine? POD in the early 1900s, Anzani never invents his 3-cylinder radial engine, so Bleriot uses some other type of engine to fly across the English Channel. During WW1, nobody builds radial rotary engines. In 1929, Lindbergh needs some other type of engine to...

It started when I was reading this post on a twin engine version of the L-1011 in another thread: then I watched this video on the L-1011: In the video, it mentions Frank Kolk's concept for a smaller widebody plane as an alternative to the 747. So it got me wondering: what if instead of...

With no PoDs prior to 1904,* what is the earliest that an aircraft could break the sound barrier? What is the earliest that ramjet technology could be developed? And this being done, how early could TTL see the first serious** designs for a scramjet plane? *or 1895 at the earliest, if you want...

As the title suggests, what would a primary trainer airplane look like if it was designed by Steve Wittman? Remember that Steve managed a busy civilian school that trained pilots for the USAAF during WW2. Steve was famous for designing a series of dirt-simple planes that won a lot of races...
