An aircraft has what is called a stall speed. this speed is the point at witch the wings stop creating the necessary lift needed to keep it aloft. depending on many factors different aircrafts have different stall speeds. some as slow as 38 knots. so essentially this small aircraft will need to be pointed in the direction of the wind witch must be a sustained wind of at least 38 knots. In theory it is possible but highly unlikely. There are dubious claims that this type of aircraft can actually fly backwards. Its all a factor of the relative wind velocity across the wing.

Aircrafts are able to hover with no forward speed.

The Harrier and the F-35Bs can both do it.

Basically, how they work is similar to helicopters

Instead of forward thrust for lift (like other aircrafts),

The thrust points downward to push the body up.

Both aircrafts' body and flaps are designed to either cruise or takeoff/land vertically

These two are the only two on top of my head, not sure if there are others like them

Oh, and one more thing: these aircrafts are called VSTOL aircrafts (stands for Vertical Short Take Off and Landing)

Hope that helps!

Airplanes, by design, can not hover. They can only achieve lift in the air by forward movement. Sometimes very large airplanes appear to hover when there is nothing in the background to judge the speed against.

1. Hover. 2. Take-off and land vertically. Although there are airplanes (such as the Harrier) which can do these things.

An airplane can have zero ground speed if the wind is going faster then the stall speed of the plane. Some planes made for the military also have thrust vectoring that is capable of allowing the plane to hover.

They can land in small spaces and hover in flight
