if you have a roof or any other solar exposed surface, go and mount panels to heat water. it's the only reasonable thing to do. solar power is great for low-temp heat harvesting and you don't need expensive (in terms of $ or in terms of resources wasted) controlling electronic. water saves 4.182 kJ per K at no cost & you will save a big lot of $$$ in heating too cold water with valuable electricity or oil! producing electricity from solar power will almost never pay out. and PLEASE: never ever lay those panels flat out on the floor or flat on a wall. it's the most stupid thing I see so often! mount it in an angle of about 45 degrees, 'cos that's the angle you gain the biggest cross-section to the average sun beam (the angle varies by your geo-spatial position and can be calculated (we did it in the university and round our place its 43.xy degrees.... everything else is just a huge waste of too expensive panels!

Because they were on manual backup control they could not exert enough force on the controls to recover before Vne or the flutter speed of something was attained.

Airbus fly-by-wire. no force needed, it's just a "joystick". probability is though, in extreme flying situation - with obviously failing electronic systems (fly-by-wire will by design be the last one failing...) they possibly lacked the artificial horizon - you loose orientation completely. if you wind down in a 1G spiral, you can't detect this. if you happen to fly into a dense cloud with a paraglider, this is how you die. with no sight and no instruments in a rather rough condition, you're doomed. you loose orientation and thus control within seconds. a A330 needs something else tho get into this condition. but once you're there you're almost dead. within our neighborhood we had at least two planes going down in the past 10 years just like this. one was an F/A-18 fighter, the other a small-sized commercial plane. they flew directly at full speed into ground
