Years ago, I recall a US Navy mechanic being sucked into the low intake of a F-8 or A-7…and he survived by holding on or someone grabbing his feet.
Wonder if the guy ever got his hearing back?

The A-6 has a set of guide vanes in the air intake. He got caught on them also the A-6’s engine has a set of guide vanes on the engine, just in front of the compressor. The CFM-56, CF-6, RB211, JT-9, ect, etc havn’t got anything infront of the fan.
