but a person getting sucked into the screen in front of an engine at takeoff power wouldn't survive anyway unless wearing a helmet / protective clothing etc...?
The chap who was sucked into a VC10 engine at BA years ago survived (badly injured) because the RR Conway has guide vanes in front of the first stage fan. As he went into the intake, his body stuck on the vanes long enough to cause compressor stall, which blew him back out again. Deaf in one ear and minus one hand and several fingers, but alive. Getting stuck on an inlet screen would have much the same effect but without the loss of any body parts.
For those who haven't tried working near the front of an engine at full power, its easy to lose concentration and get too far into the intake depression. I always tied myself to the stand when doing trim runs on the VC10.
