Here's what your flight log shows:
- You took off in a location that was near a building (see the photo below), potentially metal in the ground (I see some nearby manhole covers), and/or near parked cars.
- After taking off, you ascended to 1,640 feet straight up over top of the takeoff point. When standing directly below the Spark, the remote controller signal is not as strong. This becomes even more of an issue when flying at great altitudes directly over top of the location where you're standing.
Here's a shot you took a few seconds after taking off:
- The wind was very strong. It was causing your Spark to drift slowly at some points even while it was using the GPS to hold its horizontal position. The DJI GO app displayed a "High Wind Velocity:Fly with caution and ensure the aircraft remains within your line of sight" message to notify you of this potentially dangerous situation.
- While hovering in place at 1,640 feet, the Spark auto switched to ATTI mode due to a compass error. That was likely caused by powering up your Spark and/or taking off near a magnetic metal object.
- Once in ATTI mode, the Spark was no longer using the GPS to hold its horizontal position. It started drifting away with the wind at speeds between 30 to 48 MPH. You made no attempt to steer the Spark back toward you.
- The remote controller signal disconnected and the Spark continued to drift away. I'm assuming the building you were standing next to blocked the line of sight between the remote controller and Spark (which would have broken that connection).
Here's where you were standing when the flight log stopped logging data:
Since your Spark was flying in ATTI mode when the remote controller signal disconnected, it would not have been able to return to the home point. Instead, it would have started auto landing 3 seconds after the remote controller signal disconnected. Unfortunately, it was flying at a high altitude and drifitng at an average speed of about 42 MPH. The flight log shows it would have taken the Spark about 200 seconds to land. That means it would have covered quite a bit of ground before it was able to land.
Assuming the wind continued to blow at a similar speed and direction, I'm estimating your Spark landing somewhere in box #1 here:
If you don't find it in box #1, then search the #2 area below that. I realize this is going to be quite the task to search this large location, but that's what you're going to have to do in order to track down your Spark.
