    Several such devices can be placed anywhere in the aircraft and can deploy when they float up to the surface and are exposed to sunlight. It would be much easier to find underwater crash sites. I don't think it's too expensive to make. Certainly cheaper than searching with ships and other planes for days (as in the case with MH370 and the Airbus that crashed into the Atlantic ocean).

  • I can see many airplanes circling around to land at KORD. I am wondering if there is a good real-time website or application to track these planes with 30-second accuracy or better. Any ideas?

  • After answering this question on History.SE, I started to wonder if it would be possible to find out even more detail about the plane now that its serial number is known. I have no idea what kind of flight records the US Army Air Corps kept, however. I know most flight logs today are kept by pilot, but I imagine there would be some way to trace what pilots flew a particular plane. I have no idea if this is possible for USAAC trainer planes in the 1930s. Could I get access to these records? If so, how would I go about it? I'm mostly interested in seeing if I can find out more information

  • Are there any considerations to take into account when flying around supersonic aircraft? I know that wake turbulence from large aircraft can pose a threat to smaller planes. Is the same true of the shock waves generated by planes in supersonic flight? For instance, do fighter pilots need to be aware of the shock waves caused by other fighter planes in the vicinity?

  • Is it possible to rent a float plane with a private pilot's license? Flying floats is one of the main attractions for me to learn to fly. However, after some searching on the internet I can only find wheeled aircraft that are available for rent in my area. Am I missing something? Are there flying clubs or partnerships that have float planes available? I would love to fly floats but owning a seaplane is not in the cards for me at this point in my life.

  • We know that most of the plane accidents and deaths result from the explosion of fuel tanks in the planes, like when two planes collide, or when the plane falls on the ground. With the advent of technology, i wonder whether it is possible to prevent the fuel explosion. Can this be done by evaporating the fuel in the planes just before the collision? Or use a solid architecture encapsulating the fuel tanks in the planes, such that the fuel is not set to fire? What research has been done in this field and if so what were the findings?

  • Sometimes, when I'm flying on the airlines, I'll board an aircraft where the aisles seem incredibly cramped, where it's almost impossible to move past without bumping every seat. I can't imagine how much of a nuisance it'd be for people larger than me! I once saw an obese person a bit stuck between one of the aisles, blocking the way for others to move into the aircraft. But then I thought about what would happen in an emergency. What if there were numerous large people on board, and there was a fire? So, are there any limits to how much the airlines can squeeze their planes' aisles?

  • Without getting into the mess of redesigning existing Flight Data Recorders, I have a simple proposal that I think would help in deep water crashes. I propose that several floating cushion sets... covered mesh with an aluminum sheet embedded. This would be easier than seat cushions to see from satellites and planes, and the aluminum layer would reflect radar and make it easier to find. This alone... quite a bit of information including the final GPS coordinates before the crash. These devices would be light and cheap. I'd think current planes could be retrofitted very cheaply. The only challenge

  • When the Cirrus was first introduced, it included a Ballistic Recovery System, which shoots a parachute out the rear of the plane that can save a plane and its occupants when something goes wrong. Seeing as how this technology has been honed over the past decades, why don't all new planes incorporate this feature? I would think that any drawbacks outweigh the benefit of not losing one's life when something happens unexpectedly.

  • I thought the shape of the wing gave an airplane upward lift. How can it fly if it's upside down?
