Casting a spell while falling

[DJMetaByte]

I was having a discussion with one of my players about the rules surrounding falling and spellcasting. The main question is this: Is there anything preventing a player from casting a spell while in the middle of a fall in second edition?

I know if PF1 characters had to make a concentration check in order to cast a spell while falling, however there doesn't seem to be such a rule in PF2. I looked under the spellcasting rules and the rules for movement and falling but didn't see anything that mentioned casting mid-fall.

So let's say that one of my players spends an action to leap off a cliff, casts feather-fall with their reaction and falls the 60ft. Can they then cast fireball from mid air to make an explosive entrance?

As a GM I tend to rule in favor of anything entertaining, but I want to make sure I didn't miss anything before I have a party of skydiving pyromaniacs on my hands.

There's nothing obstructing casting while falling other than that the typical fall doesn't last long enough to cast a spell.

Spell casting is a lost less disruptable than it used to be (or rather, than it appeared to be since most of the rules that called for a concentration check or the like in order to cast a spell provided a DC that was typically pretty easy to achieve).

Nothing stops you but the floor.

The Bottomless pit trap mention some stuff about falling activities.

Quote:

The pit contains many handholds, so the falling creature can try to Grab an Edge again every 6 seconds. If the creature succeeds, it can start to Climb out from that point (though it might be a very long climb, depending on how far the creature fell). Since the creature falls endlessly, it can rest and even prepare spells while falling, though items dropped while falling are usually lost forever.

If you can rest and prepare spells, casting a spell while falling shouldn't be an issue at all.
