By sheer luck, I was in Paris a few days at the same time that the Bourget Air Show. This also happened in 2005, and I went there for a day then.
This time, I went during professional days, which meant fewer crowds (good), but a much lesser airshow (not as great, but oh well):
the line to get in was thankfully fast as everyone was pre-paid
I then went to see expo halls:
chinese jet
cool aircraft using helium for lift and hydrogen for propulsion
NGF concept
VTOL aircraft:
quadplane (multirotor for takeoff and conversion to plane in flight)
another concept
Drones:
tethered drone with unlimited runtime
It was air and space:
A fair amount of planes outside too:
next generation fighter
I went back to see the old planes that are there all year:
747 2nd floor
So, there was a small airshow, I only watched part of it given limited time and that it was a bit weak. I heard it was better during the weekend when the general public was allowed. I somehow made a few wrong turns and ended up at the Airbus private viewing lounge:
And that was it for the Bourget expo. I didn't quite have the time to see everything in one day, but saw most of it, worth the visit given that I was already there :)
