A few years ago my business partner and I had a free long weekend in L.A. and asked Group 3 Aviation, based at Van Nuys "The World's Busiest G.A. Airport" to teach us to hover......neither of us had even sat in a helicopter before.
Four 1.5 hour sorties per day with a 2 hour break between each sortie. 12 hours a day for three days....we demanded aircraft and instructors and they supplied them, on time and ready to go.
They succeeded but there's only so much hovering you can do in the early stages so within minutes we were also mixing it with the big jets at Burbank followed by pinnacles behind Malibu, running the Santa Monica beach "not above 150ft" and finally shooting night approaches into Wright Field.
As you may have gathered I became hooked on rotary with the consequent hammering of my bank balance
I've been back to Group3 twice since and they have always delivered exactly as promised
