Given that Traveller starships are powered by fusion reactors using large amounts of power, I can see takeoffs & landings having nearly as much light and sound as large aircraft taking off, both with whatever glow the drive makes, various operating noises, and the in-atmosphere radiator systems doing their bit to cool the various hot bits of the grav drive and the fusion reactor.hiro said:Well, it's not quite the same as sitting by the runway as a youth being awestruck by an F-15 taking off with afterburners, now there's cinematic! What a noise!
Also, regardless of how exactly you think jumpdrives work - I can see going into jump looking pretty darn spectacular from anything remotely like close range - I'm guessing that at least some of the hydrogen used is vented to carry off waste heat (and may well be vented as plasma), and I'm also guessing that the jump grid or jump bubble glows in odd and very bright patterns as the ship gets ready to jump. Perhaps it's even as bright as a modern chemical rocket taking off - although obviously far quieter for observers.
