Elon Musk, 3 years ago: This is banana stuff. It probably won't work the first time.“Instead of putting landing legs on the booster and ship, we are going to catch them with a tower to save the weight of the landing legs. We're talking about catching the largest flying object ever made on a giant tower with chopstick arms. It's like Karate Kid with the fly, but much bigger. This probably won't work the first time. Anyway, this is bananas. This is banana stuff.”
