Regular helicopters make more sense to me. They're already used extensively with offshore platforms, so why invent the wheel? The jet fuel they burn is a pittance compared to the hydrocarbons being burned by the rockets. And they have a much better carrying capacity; a Sikorsky S-92 can carry 19 passengers in one trip. Electric helicopters could do what, two or three per trip? Maybe a few more with future battery tech, but I don't think conventional helicopters will be phased out anytime soon.

Because that's Tesla's business. Plus halo effect - you don't want to board a spaceship by flying on a helicopter designed 30 years ago.

Remember that battery weight scales linearly with number of passengers, so building a larger battery operated helicopter just needs more motors and batteries. We don't have large e-copters because it costs a lot of money to certify one for 20 passengers and, until now, there is very little demand for that.

Could use a high-speed hydrofoil too. Helicopters aren't the safest mode of transportation, and are horrible in bad weather that a boat would brush off with ease. Plus if we're sending 100 people on a flight, that's quite a few large helicopters plus landing facilities.

Absolutely, a high speed ferry could have great throughput; it seems like a great choice if they're going to put a few dozen or more people onto one of these rockets.
