The catching with a helicopter part is complex, but not time-consuming - either it works or it doesn&#x27;t. The rest is probably if anything easier - I&#x27;d imagine SpaceX will have to tear down the booster entirely for inspection, at least for the first few hundred. These things are (or will be) built to be disassembled and reassembled, attaching engines and pumps to a new tank is not going to be a long and complex process.
