Ok, maybe not really tool material, but it drove me nuts. During the route check, the Captain that can not pronounce ANY five letter waypoint correctly...

Point: TOMUD

Captain: "TAMID"
Me: "Is that TOMUD?"
Captain: "Yeah"
Me: "Check"

I'm thinking that's not a big deal, it was close... then:

BIGRO
Captain: "BAGRID"
Me: What the??? "BIGRO? Check"

ALEKI
C: "ALEXIS"
Me: Sure... what the heck "Check"

NIKUK
"NOKUD"
"Check"

UVUNO
"UVILL"
"Check"

ADBAG
"ADGOG"
(Holy crap... that's not even close! Are we going to the same place?")
"Check"

And it went like that for about 10 pages worth...
