My experience too with law firms and accountants. I have a feeling they hate paying by the hour.
But they sure don't mind charging by the hour (in 1/6 hr increments no less)
" so it'll be tough to build an internal team quickly enough "
This smells of failure. Contractors aren't going to get up to speed any faster than internal resources (sans technology specifics like expertise in a language). Our management tried the same thing: hire contractors for a short term (less than 3 months), hurry up scenario. Except it took a month to interview and get the contractors on site. Much of the 3 months of contractors time was spent to get their environments setup, work with IT to configure permissions and the contractors themselves to learn the complex product enough to contribute. Not to mention the loss of focus of the internal team assisting the the contractors.
I would spend more effort coming up with a realistic plan that has a chance at success rather than trying to meet a date that is not going to be met. Build a plan that includes a mix of internal an external resources. I would include time to hire contractors (remembering that background checks take time) plus all of the other activities that will consume time away from producing the finished product.
drones are bad! that's the mantra and the panic that ensues. I say follow the money and see who stands to gain or lose from drone users (from hobbyists to professional and government uses). There you will find your real motivation for such panic.
I've struggled with how pilots flying at 100+ mph can honestly report sites of hand size drones and consider it legitimate information. I remember a fire fighting pilot being interviewed about how unsuccessful the fire fighting effort was because of drones-- let's see there's smoke, fire, debris, stationary obstacles and everything else and he actually had time to recognize hampered by drones. I think it's panic, fear and just opportunity to blame something new with lots of unknowns, than than realistic (before everyone gets all cocky eyed, I do hold a recreational pilot license which I've had since the 90s, PDK of all places)
That's not to say there is potential for a drone could cause harm. However, I'm sure the panic is driven more by money and control than common sense.
We have little drone, weighing at most 3lb. And then we have a jumbo jet, weighing tons. The jumbo jet creates all kinds of turbulence and wind eddys. The little drone can barely hold in any wind.
I realize if one of these gets into the engine of a plane it could be devastating. However, being an owner of one of these "drones", I have a hard time seeing one of these ever getting to that point. The higher you get with the drone, the more wind to contend with. Wind and drafts will throw a drone so far out of control it will be like a piece of paper blowing in the wind.
