# Mission: Impossible 3

Yesterday Ethan Hunt received the following message:

Take Qantas flight number 47, leaving 11 o'clock on the 5th of April. At your destination airport use any bus with number 2, 8, 18 (or bus 18/1). You can take with you 107.8 kilograms of luggage.

What is the goal of Ethan's journey?

• @AE I'd put it in the same category as enigmatic puzzles like this and this. Arguably it's a cryptogram, but one could also argue it's more like a riddle since all the clues point to the same answer. Never mind - the current tagging is a good compromise :-) Mar 25, 2015 at 11:40
• @randal'thor fair enough :)
