It’s just not that effective of a strategy. They tried it a few times in the 70s, but most of the time, they got caught before they had a chance to fire, or they couldn’t hit the target. In one case, Carlos the Jackal fired an RPG at an El Al jet, but ended up hitting a Yugoslavian plane instead, which surely pissed off his communist paymasters.
I wasn’t thinking RPG’s. I was thinking shoulder launched SAMs. I thought they had a maximum altitude of 10,000 feet and that shold be no problem for a plane taking off. And you can easily hang out at the end of a runway in an urban area in LA, Seattle, Burbank, Ohare, etc.
I thought they had those sorts of SAMs for a long time. If I’m full of baloney, never mind... ;-)
