When I flew back from Cape Town a couple of years ago I was watching the lightning flashing way below us. Only time I've actually watched it from above.
Went on a holiday by charter 'Laker Airways' many moons ago.
Their plane was not working and they subcontracted a Canadian Pacific Airways plane to fill the gap (those were the days).
The subcontracted plane was equipped for a scheduled flight and the quality of service was far more than we were, of course, expecting from Laker.
As we approached the destination the captain informed us of a gigantic thunderstorm that was happening over the island. He look us around the storm and we watched the sky light up like a giant pinball.
He gently guided us around the storm, with hardly any turbulence and landed as smooth as silk.
Anyhow, also at the end of the holiday, there was another huge storm....but unfortunately Laker's plane was working this time ... it was an old Boeing 707 and the pilot flew us directly through the storm.....we all thought that we were going to perish as the plane bucked around and literally dropped many times causing a bit of weighlessness, let alone stuff flying all around the cabin area.
Laker was the first cheap airline but you usually did get what you paid for...sometimes
