Skyline Threat

An investigation authority found an image from a terrorists’ email without any context but with the title “Next attack”. They have to find out which airport, which airline hanger and which aircraft. Are you able to assist them in this investigation ?

The flag format is CTF{AIRPORT_AIRLINE_AIRCRAFT}. AIRPORT is the 3 letter IATA airport code, AIRLINE is the 2 letter IATA code, and AIRCRAFT is the aircraft model and variant (omit manufacturer name).

For example: KLIA, Airasia, Airbus A320-200 -> CTF{KUL_AK_A320-200} KKIA, MAS, Boeing 737-300 -> CTF{BKI_MH_B737-300}

This is the image given. If you zoom in, you can see a logo with three boxes.

Throw the picture into google lens and you will find that the company name is called Cargolux Airlines. The IATA code for Cargolux Airlines is CV. I also found out from google lens that this airport is in Luxembourg through this link:

The only airport in Luxembourg is called Luxembourg Findel Airport.

Now that we got the airport name, it’s IATA is LUX. Next, we are going to find the aircraft. This airline commonly operates Boeing 747 variants for cargo transport. From the image, it seems likely to be a Boeing 747-400F (freighter) or a newer 747-8F, both popular models used by Cargolux.
