According to Wikipedia:
Some aircraft are able to safely use reverse thrust in flight, though the majority of these are propeller-driven. Many commercial aircraft cannot use reverse thrust in flight
What are the repercussions to using reverse thrust while airborne?
The problems are two-fold:
The airspeed is much higher in flight than when landing, so the thrust reverser doors would have to be much stronger, and therefore heavier to withstand the additional forces, along with the relative wind making them harder to close.
What happens when it gets stuck in the deployed position? Now you have to shut down a perfectly good engine and have additional drag on the airplane while in flight.
(Bonus) It isn't really needed on most airplanes with spoilers, flaps, etc. that accomplish the same thing.
The reversers on many jets significantly disrupt the air flow around the wing and are generally too powerful for use in flight.
There was a crash, Lauda Air Flight 004, that was caused by uncommanded reverser deployment in flight. Granted, it was asymmetric deployment, but the report cites loss of lift from reverser deployment (itself, not loss of speed due to it's prolonged operation), which would occur for symmetric deployment too.

This comes from a flight simulator experiment ages ago in the Boeing 737.... I'm on the runway. I engage the heading switch, followed by the altitude and thrust. The aircraft lifts off, although hardly in a clean rotation. Now I'm wondering: While it did work in the flight simulator, will the autopilot follow these commands in real life as well if I repeated this in a business or commercial jet? Is there anything stopping the autopilot from engaging a specified altitude or from following instructions which are utter nonsense?
According to Airbus: ‐ After the flight crew selects reverse thrust, they must perform a full stop landing. Does it really make sense to have this limitation, and why? What happens if you realise there's not enough space to land, and you've still got adequate speed?
at a specific location and time may differ appreciably from those computed by PC Windtemp. Therefore, data from PC Windtemp must not be used for flight planning, aircraft dispatch, airborne flight navigation, or any other type of actual flight operations.

There are a number of different ways of taking off with a powerless hang glider, the most commonly used being either running down a hill or jumping off a cliff/platform. This is how I learned to hang glide and is the standard way of getting airborne for most hang gliders. However, I recently moved to the Houston, Texas which is extremely flat. As far as I can tell, there isn't a single hill tall enough to take off from within a 100 mile radius of where I live. How can I safely get airborne when I am on flat ground?
As an instantiation, the Boeing 737 persisted in operation and to fly for several years despite rudder issues which had not been safely ascertained and resolved. It's conceivable that flyers who avoided the aircraft had had less probability of injury or death while flying.
Recently, the crew of an Indian airline performed a short choreographed dance sequence mid-flight on the occasion of Holi. This is, a not so rare practice amongst low-cost Indian carriers, who... of the pilots can be seen recording the dance on his camera. SpiceJet specially planned this event, and had extra cabin crew on-board the flight as a precaution. Also, during the dance, one of the pilots was in the cockpit while the other one was outside, following standard regulations. DGCA however, got wind of this, and turned out to be not in a very festive mood. Mid-air Holi celebrations
Another enthusiast question. I watch a lot of the National Geographic Channel's "Air Crash Investigation", for better or worse, and it seems accident investigators make tremendous use of the Cockpit Voice Recorder "CVR" and Flight Data Recorder "FDR" to determine the chain of events leading up to- or the root cause of an accident. One of the more recent episodes of ACI (Season 12 Ep. 13... which periodically transmitted maintenance data to a remote Airbus location in Paris to alert ground crews of possible maintenance issues with inbound aircraft. Given that Airbus already uses similar
If I understand correctly, when a plane transitions from takeoff roll to being airborne, it is not something that happens "by itself" when the airspeed is high enough, but is caused by deliberate... the tailplane down, which makes the entire aircraft pivot around the main gear and increases the wings' AoA enough to create lift that takes the plane off the ground. Or is it something that increases lift with unchanged attitude, such as a symmetric aileron movement, or an additional flaps extension? And then after the plane is airborne it is rotated to climbing attitude? The descriptions I can
