Having experienced a similar situation recently - thankfully not a crash - I suspect that some sudden motor cut outs may be caused by insects!
Flying in 100m high it is impossible to see a large mosquito or a huge fly but it may be there. In addition, keep in mind that everything above the drone is getting sucked by the blades, when the software understands that a motor looses spins then the motor is out. This is a safety feature which is very useful when the drone flies around people or indoor but it is catastrophic when it is 100m high above the sea!
Possibly, in these cases - high altitude - Parrot should not cut out the motor! - The motor should stay active struggling as much as possible while the other motors adjust for a controlled emergency landing.
What do you believe?
