Just a few personal comments based on a career as a NAVY, commercial, instructor and test pilot who is married to an aviation attorney.
1) Drones haven't killed anyone - yet! Give it time. There is a significant effort in process to prevent that from occurring. By-the-way, this statement isn't entirely true.
2) The FAA is not short handed due to it's efforts to regulate the recreational drone industry. But they are understaffed and funded but that's another story.
3) Was the input test data on the MCAS system rigged? Perhaps, but in the movie Draft Day, the saying "when you get the answer you want, hang up", may apply here, to quote a whistle blower VERY familiar with the Max testing program.
4) Boeing pulled a bit of a trick play regarding the 737 Max program. Hence, it was classified as an "update" to a previously certified platform (yeah right - I've seen the the technical specs and, as a former test pilot, know how to interpret them). I can say with good authority that Boeing applied pressure to it's 737 Max team to deliver the model in direct competition with the Airbus A320 neo (New Engine Option.) Side note - I was on the engine test team and asked the engineers at Airbus "lame name, can't you come up with a better one?)
5) The modified air frame had some tricky stall characteristics, hence, the MCAS system. Boeing was behind schedule and someone "greased the skids" to obtain certification (in my opinion) and convinced the FAA they could "self-certify". That's a bit like asking the fox to guard the hens.
6) in their haste, Boeing has pushed orders for the A320 neo through the roof and all but killed (no pun intended) the 737 Max program at the same time. The very inverse of their marketing objective (seems Darwin missed a few). Not to mention the loss of life.
That's my rant on the subject. Anymore and I'd likely get slapped from my wife.
