I've seen as many as 60 in a string being launched, that was a long line string. I read. 20-40 is normal release. It's amazing a private company has basically taken over NASA jobs for space launching. Yesterday his company picked up 4 astronauts from the space station and delivered them with parachute landing off the Atlantic coast of Florida. went off without a hitch.I watch almost every night. Some nights better than others. musk is going to be launching 45,000 communication satellites before he's finished. here's a link to a website that you can see the times and direction to look.
