In a quick update to yesterday's post about Solar Impulse waiting for the right weather conditions to fly to Brussels, I received a press release from them today saying that "a favourable weather window seems to be opening up for Friday 13 May".
If conditions remain favourable, Andre Borsch plans to take off in the solar-powered protoype, HB-SIA, from Payerne airfield in Switzerland early tomorrow morning. The flight is expected to take about 12h.
Solar Impulse will be providing live updates of the planned flight's progress on its website. I'm hoping to speak to the pilot early next week to find out how it all went, and to see what the plans are for the protoype's debut at the Paris Air Show.
Here's wishing them the best of luck. They're obviously not a superstitious bunch.
