Spot on - OP: NFZ's have never caused me any issues even flying within the M25 orbital and in zone D airspace. As long as you are a good 4 miles from an airport etc then you'll be fine. NFZ geofencing is in place to protect manned airspace so its best not to try and break it. In fact, if you don't upgrade the FW you may find yourself with flight restrictions as the FW on the Mavic towards the end of last year was mandatory according to the DJI release notes.
Yes, the falling drones were Sparks before DJI put madatory FW in place on that drone w/e 01 September '17... Another great app I use is NATS drone assist - even the government recommend it - it outlines all NFZ's within the UK from petrol stations and pylons to airports - that will tell you everything you need to steer clear from as part of your preflight checks.

It seems some users are starting to worry about the possibility of their Mavic dropping from the sky, given the recent incidents of unexplained inflight shutdowns. Some say it's nothing to worry about, whiles others are starting to feel jittery.
I decided to post this thread to share with you all the data that I've been gathering on this issue. Shortly after I started to see a few of these cases being reported on MavicPilots and the DJI forums, I decided to start logging as much information as I could, fearing there could be a trend. My data so far includes 14 reported incidents. One of those happened back in February, while all the other 13 were posted in April. Now, I'll be the first to admit that 14 reported cases is not a huge number, given the thousands of Mavics that must be in the air every day. However, 13 reported cases within just a few weeks does not seem insignificant, and we don't know how many others have never been reported.
In pretty much all of these cases, there has been no root cause attributed to the crash, aside from the obvious complete power cut. @BudWalker, @Robbyg and some others have looked at several of the available .dat files, and while there was an apparent anomaly seen in some of them, it isn't present (or missing, to be more accurate) in all cases. DJI seems to be covering these recent crashes under warranty, indicating there was no pilot error.
I don't want to be alarmist, and that's part of why I didn't post my findings earlier, but I now think perhaps it would be good for everybody to be able to track this data as well. I will leave the data here for others to decide what they think.
Here's a link to the data: Mavic Karma - Airtable
