Not implying I am an old fellah, or anything, but it does remind me of when White Star were excused from fitting enough lifeboats for the Titanic.
You'd think the Gol crash would be enough, but a highly resistant strain of bureaucrats now have greater immunity to common sense than they had in 1912.
That said, it does seem ridiculous to me that a high-performance jet of any type, especially a single-pilot one in busy European airspace, does not have TCAS.
Sorry to make light of a serious topic, but the above topic got me thinking about TCAS in jet fighters...
I couldn't stop grinning when I thought about the collision advisory alerts during a dog fight:
"Sorry skipper... my sidewinders couldn't get a lock on because of all the TCAS alerts." ha ha
