My only fear of a towed method would be entanglement. Powerlines, limbs, etc are all typical things you'd find in a bigfoot search area. A remote controlled vehicle like a copter or plane I think would be a great way to cover a a lot of area from above.
I doubt there are many powerlines etc. in the remote areas DDA has been scouting, at least from what I have been told. Remote control copters and the like are noisy (emitting an alarming unnatural whine) and would be expensive and difficult to recover should they happen to fall into a swampy area etc. Silent "floatables," such a the streamlined rocket shaped balloons in the pic DDA posted, or some form of stable glider or kite would provide much more stealth. Heck, even a stabilized extendable pole camera of some kind could allow considerable views over hills, knolls, tree patches; as well as infared detection for night ops etc. I think it's an idea worth experimenting with at the very least. From what I understand, DDA's persistent and systematic methods may just be the most likely to produce clear photographic evidence of this elusive creature. (Hint, hint...any investors out there who want to throw money at one of the current research projects that has the best chances of producing results, I'd seriously look in DDA's direction. JMO of course. If I had the extra $$$$, I'd do it.)
