Seldom
Well if he could, why did he hit it?
Please no red on the ifs! Lots of ifs lead to me thinking that we are running out of them, and one of the careless scenarios below must be true.
If he flew into the terrain that he could see, he was very careless. If he flew on into fog and took no remedial action, he was also very careless. If he had his head in the cockpit at this stage of flight, close to land and at relatively low level, he was again very careless. What other scenario can you come up with?
Polite, eh?
