Cracking Codes like GCHQ [Part 2]

Part 1

One of our field agents intercepted the following communication near the airport. Who is being communicated with, and what are they being told?

Grlr9UOaoC1num,enrRwcuhihneliwglnaAbgyief1

Where are they going?

Npxabjyrqtrq, zbivat gb Crevzrgre Tngr N5

Do they have anything of concern with them?

USJ lq srvlwlrq

That is an issue, we’ll send a team round straight away! Do you have a precise location?

#968p:C ~?6 =@42E65 H:E9 362C:?8 _`g] !6C>:DD:@? E@ 7:C6n

Permission to fire? This sounds like it could be a threat on the President’s life. We’ll update the National Threat Level to CRITICAL. I’ve got to head to the bunker, just in case, but please continue to feed useful details to R.

What does this latest message say?

Otkr.nitaeielcmet f lemd o ai o of,twctf

They don’t seem to have taken a shot yet. What are they waiting for?

We’ll delay takeoff until we know more. Anything on this intercept?

We seem to be confusing them. Is this transmission exclusively noise, or is there something useful in there?

The plane seems to have taken off correctly, but there’s another transmission just come in. Should we be concerned?
