I had a female passenger get violently sick during a scenic flight over Sydney a few years ago. Not long into the flight she said she wasnt feeling well and I decided to expidite our return but vie the normal route -outside controlled airspace.
However as we orbited over the Sydney Harbour Bridge she became violently ill to the point where I was worried she was going to choke on her own vomit. I informed ATC that we had a sick passenger and requested a track direct to Bankstown, which cuts across the ILS of 16L and 16R at Sydney International. Its pretty rare that this would be granted but they gave me an immediate clearance, vectoring 2 QF jets with some track lengthening to enable me to get accross.
Less than 5 mins later we were on the ground thanks to some expeditious handling by the Sydney and Bankstown ATCO's. Turns out she had accute food poisioning and spent the night in hospital.
Thanks to the ATCO's that made my job so much easier in a very stressfull situation.
