noticed the CO flight push back, then taxi very slowly before performing a very ballsy u-turn in the cul-de-sac where stands 9-15 are located and then returning to stand 22 where it sat for an hour and a bit, engines started on stand with GPU connected then a boom-lift appeared at the back of the a/c, must have been APU problems
also BFS was down to 2 free stands this morning for nightstoppers (11 and 10) was a TCX on 9 this morning
