Don't you watch hours long stuff all the time on telegram? 
Anyway, the folks aboard the 1986 Challenger explosion were not aboard and are alive and well and in academia and business...same names, same age...all because a school chose to take Christa McAuliffe's name off a school and made a dude investigate why...
Thanks for the summary. I watched lots of telegram video interviews early on to learn who the players were in the Ukr war. Lots from Mariupol. Now mostly youtube music videos. I can usually skip those YT ads after a 5 second count down.
The two ads in the above video were insulting. The second one showed how to cool a room using almost no energy. Then the video dragged on.
On telegram I now prefer putingers cat and Lord bebo. There later usually is also on twitter to share easier.
Did you know Christa McAuliffe had blue eyes? One blew this way and one blew that way.
I forgot the others.
