haven't been on the net in a while (damn windows 7), but just two anecdotes......a few weeks after i started working at 34th st heliport, a pilot in a jet ranger "b" model, lost his engine over the hudson river at about canal street, made it back to 34 st, put it in the river just short of the heliport, he and two mechanics made it out ok......second was pilot on a sightseeing flight with a dauphine (they were bottom of the battle consripts from who knows where) had transmission start chewing itself up down around the brooklyn bridge.....brought it back to 34th st about 30 feet above the river, and actually managed to land it on the pad.....of course, he was an ex-tuskegee airman, so i guess he was used to problems; in his 70's, he was still cool as a cucumber, and only a half hour after landing did he come in to me in ops and start shaking (just a little).
