An air traffic control tower suddenly lost communications with a small twin engine aircraft.
A moment later the tower land line rang and was answered by one of the employees. The passenger riding with the pilot who lost communications was on a cellular phone and yelled,
"Mayday, Mayday!! The pilot had an instant and fatal heart attack. I grabbed his cell phone out of his pocket and he had told me before we took off he had the tower on his speed dial memory.
I am flying upside down at 6,000 metres and travelling at 240 km/h. Mayday, Mayday!!"
The employee in the tower had put him on speaker phone immediately.
"Calm down, we acknowledge you and we will guide you down after a few questions. The first thing is not to panic, remain calm."
He began his series of questions.
Tower: "How do you know you are travelling at 6,000 metres??"
Aircraft: "I can see that it reads 6,000 metres on the dials in front of me".
Tower: "Okay, that is good, remain calm. How do you know you are travelling at 240 km/h??"
Aircraft: "I can see that it reads 240 km/h on the dials in front of me".
Tower: Okay, that is good. How do you know you're flying upside down??"
Aircraft: "Because the shit in my pants is sliding out of my collar."
