Flying games split cleanly into two kinds: the ones where the aircraft is the subject, and the ones where it is a way of moving through something. There is one of the first here and two of the second.
Airfoil is the simulator. Four aircraft with genuinely different handling, lift and stall modelled rather than approximated, and engine loops cut from real flyby recordings. It will let you stall it, and it will not save you.
Propeller Pilot is the arcade one — a little red plane through a candy-coloured sky, energy draining the whole time, rocks tumbling toward you in loose clusters. One control, the mouse, and a world that accelerates until it catches you. Balloon Convoy barely flies at all: you stack balloons, ride the wind and try to keep the convoy off the rocks, which is closer to a puzzle than a flight model.
All three are free, unblocked, and need nothing installed. Airfoil is the one worth a keyboard; the other two are fine on a trackpad.
