Why don't aircraft use nuclear propulsion?
TL;dr - too heavy :-)

Are the guns on a fighter jet fixed or can they be aimed?
They are fixed, and many attempts were made over the years to have an aiming capability - and all failed. That should tell you something.
The earliest aereal combats used indeed handguns which were ...

Why don't aircraft use nuclear propulsion?
To a large extent, it wasn't revived because the only realistic use case became obsolete. The USA and USSR were both interested in nuclear-powered long-range bombers. The plan was to have a fleet of ...

Why is this missile positioned in this odd position? How can it be launched correctly?
You're seeing the Sidewinder on the folded up wingtip of the F-18 that is in the foreground out of frame except for its wing tip and missile sticking up at the bottom. The airplane is between the ...

Are the guns on a fighter jet fixed or can they be aimed?
The guns of modern fighter jets are fixed to the airframe—they can't be moved in any direction; the pilot has to maneuver the aircraft to bring the guns to bear. The image shows the mounting of ...

On the F15-E, can the WSO take over if the pilot is incapacitated?
Short answer, yes. However, it is important to note that the WSO is not a pilot. The WSO is trained to operate the weapons systems, not fly the aircraft, but does have basic flight controls ...

Can someone/something other than the pilot trigger the ejection seat?
In a word, yes.
There is a switch which controls this and the default position is "both". If any handle is pulled (pull down over the face or the one between your legs), then both seats ...

What does this hand gesture of fighter jet pilots mean?
It is the signal to perform a fuel check. (Actually: "How much fuel have you?")
The hand mimics drinking from a bottle, and when given by a formation flight lead it is intended to prompt ...

Can a jet stream make a subsonic plane fly at a supersonic speed relative to the ground?
Yes, the ground speed of a subsonic aircraft could be larger than the speed of sound. As an example, during the record time for a subsonic Atlantic crossing a Boeing 747 reached speeds of up to 1327 ...

Slanted Brown Rectangles on Aircraft Carriers?
The rectangles are called impact pads. The ends of the arresting cable tend to snap back onto the deck after an aircraft catches it. The replaceable polyurethane pads protect the carrier deck from the ...

Were propeller airplanes significantly more "scary" to fly in compared to modern jet ones?
Old propeller airliners were much more prone to "bumpy" ride than modern jets, for one major reason: they flew lower.
When I was in my early teens (almost fifty years ago), I flew several ...

Why do many fighter jets have double vertical stabilizers?
There are a few reasons many fighter/bomber designs have 2 vertical stabilizers:
one large tail produced more shear force at the root, 2 smaller tails mean less force at the vertical stabilizer root. ...

Can a missile be fired when a fighter jet is inverted?
The combat advantage of fighters (as opposed to heavier-payload bombers) is their maneuverability, therefore a missile delivery restriction such as g-limit (think Sidewinder heat-seeker in a dogfight) ...

Is it possible to fly around the world to stay in daylight with a fighter jet?
