Having known André for a long time, I am always admiring of his performance, but never surprised by it.

I have in fact found it rather amusing to watch the excitement, even nervousness at times, of the medical teams over the past few days. They lay in wait for the slightest sign of failing in order to respond immediately, but I knew only too well there would be none!

With the yoga exercises in the simulator, André was as much a fakir as a pilot, and a fakir never cuts himself with his sword...!

The other aim of the exercise was to train the task team in situations of fatigue and stress. Once again, total success was achieved. Proof of this is the atmosphere of solidarity and concentration that brought all the participants together over the 72 hour period, which is already fostering feelings of nostalgia in them all.

We will see over the next few days whether some of them come to the task centre for a few hours a day to avoid too abrupt a withdrawal! You too should manage the withdrawal ahead of the flying tasks this Spring over the Mediterranean.

Great team spirit happening! The only causality thus far is the coffee machine, which has been working non-stop and could really use a 100'000 km check up!

A last burst of energy and inspiration to share with you the last subject on my list I absolutely need to learn a little "endurance" from André.

One of all the many aspects in keeping André sustainable for so long is the cockpit. This week we have been testing a prototype cockpit for the 2^nd airplane. Compared to the 1^st cockpit in HB SIA, this is definitely upgrade from economy to business class!

In collaboration with Lantal, a partner company, a special seat was developed and tested during the simulation. This seat is built with an inflatable pneumatic technology offers several positions (flying, relaxation and resting) and has an integrated toilet. Wow, no morewaiting in line to go to the bathroom!

As to avoid any health issues that can arrive from immobility, André has been pursuing a series of exercises developed by Doctors and Osteopath from Hirslanden. Watching these exercises on our screens from André's on-board cameras, these look really strange and one may wonder what he is really up to ! Actually my theory is that he is using some of those techniques he picked up in India.

Landing expected at 08h00 (UTC+1). Go for it André, less than 90 minutes left.

And for Bertrand, we will see you later this year here in the simulator. But in the meantime we have a few real flightscoming up soon

Steady state is for a human being what sustainability is for humankind. It means that the physiological parameters of the human body have reached an equilibrium that allow them to continue to work the same way for a long period. When you run, a sprint is not a steady state, a jogging is.

In our case, it would be possible to make a sprint where the pilot doesn't eat neither sleeps for 72 hours, but it would be useless as this situation could never be sustained if the flight was to last longer for a reason or another. The pilot would be so tired that he would never be able to land the airplane.

So the goal here is to push the limits for the lack of sleep, the food patterns, the hygiene in the cockpit, the use of the toilets, the shifts of the mission team, but without going too far. Until now, not too far is already quite impressive!
