if i may weigh in on this subject as a commercially licenced helicopter pilot with 5000+ hrs of PIC (pilot in command) time, i'd agree with Paul161 that helicopters both civilian and military (Blackhawk in this case) are very safe if flown according to the published limits according to type. they are extremely complicated peices of machinery that are well designed and well built. indeed maintenance is a key factor and depending on the type (# of engines, IFR vs VFR, etc etc etc) the time required for appropriate maintenace varies greatly however, if you are operating an aircraft that is built by one of the major manufacturers (sikorsky, Eurocopter (my preference), Bell, Agusta etc) you can be sure that you are as safe as circumstances allow. just like vehicles they are subject to mechanical issues which in most circumstances can be handled by a competent pilot(s) depending if timing, abilities and, conditions allow for it. indeed i am not ranting at you guys but the press love to cover these types of accidents because they make good pictures and most of the public find this kind of coverage to be of interest. as a helicopter pilot who has lost friends in accidents that occured under circumstances where the blame can be placed on both pilot/maintenace and machine i still feel safer in the pilot seat than i do in rush hour traffic around toronto or detroit. indeed, if i didn't i wouldn't do this:
