What was he/she doing? No radio,

Yes, but in the dark?
I guess you could use the landing light beam to judge attitude better...

Wheel landing practice? My tail wheel instructor had me do that. We'd
make a wheel landing and then balance forward stick and enough power to keep
the tail up while increasing speed and holding the mains on the ground, then
lift off and immediately make another wheel landing until we ran out of
runway, then back taxi and do it again. Then we'd switch to the crosswind
runway and do it on one wheel. We never got 50' off the ground though, nor
did we do it at 1am!
