Boy does this bring back the times in Guam with B-52's, we had all kinds of problems with bugs blocking the PT2 probe had to disconnect and blow out each one and as the old bird had 8 engines it wasn't a great job. Answer was for the really good gound crews to put blanks on till preflight. The question is will aircrews take the blanks off??????????? There is no answer to that one.
Keep them going boys
