# Flying
Flying is an intrinsic property that appears in NetHack, Monsters that fly are defined in the source code with the  M1_FLY flag.[1]
Flight allows a monster to avoid contact with the ground as with levitation, but additionally allows control over vertical movement - while flying, you can pick up items on the floor, go down stairs, use ranged weapons without hurtling in the opposite direction, and so on. Broadly speaking, flight gives almost all of the benefits of levitation with none of the downsides.

Description
The detailed effects of flying are as follows:

You can pass over pits, holes, trap doors, squeaky boards, and bear traps without triggering them. (Pits and holes in Sokoban will still trap you.)
You can pick up items in pits and spiked pits without falling in. If you begin flying while stuck in a pit, you can escape in one turn.
You can descend into holes and trap doors with the &gt; command.
Land mines have a chance of not being triggered, and will not wound your legs.
You can move over lava and water safely, and you can dip items into water.
You have a better chance of avoiding being killed by a collapsing drawbridge.
You can move freely over ice and on the Plane of Air.
Wounded legs do not reduce your carrying capacity.
You suffer no ill effects from descending stairs when encumbered, fumbling, or punished.
You escape the dungeon rather than dying if you level teleport to a level between −9 and −1.
You cannot snag underwater items with a bullwhip unless you start levitating.
If you begin phasing through something solid, you will stop flying until you are in open space again.
Even though all e possess the M1_FLY flag, they levitate rather than fly.

The following information pertains to an upcoming version (NetHack 3.7.0). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.

Flying can be gained extrinsically by wearing an amulet of flying.
Bugs
You can sometimes displace flying monsters by kicking them. If the "foo swoops, nimbly evading your kick" then it is moved to a vacant square randomly selected from those nearest to you.[2] This means that on sufficiently crowded levels, it is possible for a flying creature to swoop through a wall. (This is possibly an effect of bug C343-38; it is hard to tell from its description.)

Variants
The amulet of flying is an item that originated in SLASH'EM and has since appeared in many variants.
Various new flying races and monsters (and thus additional polyforms) are often added in variants - the vampire  player race]] has intrinsic flight in all variants.
