One of the best shareware air combat games ever made, Corncob 3D (a.k.a. Corncob Deluxe, name of the registered version) is a great 3D flight sim set in an alternate world history (that seems a tad far-fetched ? but hey, it's just a game ;)). Jeremy Johnson eloquently sums up the game in his review for MobyGames:
"Corncob 3D/Deluxe is an early flight sim where WW2 never happened because Hitler had a fatal injury in his youth. However, in it's place, aliens have decided to invade Earth (again) because they need someone to clean their toilets (not really a joke). However, despite the fact that they can travel light years in a short span of time, they can only seem to muster projectile weapons in their invasion, and a simple 500 lbs. bomb can blow up most of their structures. Therefore, they have been unable to completely take over as of yet. Also, out of all of the planes that were developed during World War II, the only one to make it into this alternate universe is F4U Corsair. And this sets the stage for you. You come on to the scene as a pilot fighting against the aliens, based at locations dangerously near the front lines. In Corncob Deluxe, these locations include a grassland, a wasteland, an area in which missions can only be flown at night, and the aircraft testing area at White Sands, New Mexico.
As far as gameplay goes, the missions are pretty unique and varied most of the time. Although most of the mission objectives involve blowing stuff up, the location and manner that you must blow them up in is quite different. For example, in one mission, you must fly to the highest point your Corsair can go to attack an alien power plant. In another mission, the power plant you must destroy is invulnerable to normal weapons, so you must hit it with your plane to destroy it (and eject just a moment before it hits the facility). In another mission, you must fly into a teleport gate that's near heavy amounts of alien defenses."
Although the game is a little too short (only three campaigns), most missions are quite difficult to complete. With a wacky plot, a unique premise that pits WWII planes against weird aliens, and reasonably realistic flight dynamics, Corncob 3D is an enjoyable, "light" flight sim that is well worth a look by every armchair pilot. Thumbs up!

I remember buying Corncob 3d from Walmart. I loved this, and Chuck Yeager's Air Combat
Turns out the editor manual is in the game, but if anyone can locate a pdf version of the printed manual, let me know.
One of my favorites from the 90's. If anyone can find the mission editor manual, please let me know. I had lots of fun back in the day playing with the editor. I seem to recall it could be accessed via command-line but I forget the actual commands needed.
my favorite DOS game where different atmospheres and gravity promotes fake difficulties
Loved playing this as a teenager.
Many nights up all night doing missions. Dropping bombs. Shooting UFOs. Neat nostalgia
