I just read something (can't remember where) that sought to eliminate
land-over events by flashing the VASI/PAPI whenever there was an
airplane in takeoff position. Sounds good to me.

Agreed, but what I meant was to flash *just* the red portion when below the
glideslope (i.e. red always flashes).

If both red and white flashed when someone was on the runway, all the
better.

In either case - when you see flashing vasi / papi lights (regradless of
color), add power and pull up!
