You do have to be careful though. We sometimes use 30Mw lasers for
astronomical pointers on clear nights and you definitely do not want
to look into one of those. They cost a tad more (between $200 and
$300 USD) than the typical little one used for pointing as screens and
are a whole lot brighter. The green light also carries a bit more
energy than the red ones. But even at three miles it'd light up most
of the cockpit and wouldn't show as a moving spot inside.
I don't think the 30 Mw would do permanent damage at 3 miles, but
you'd need to turn up the cockpit lighting to read the instruments if
you looked directly at it.

I hope you are talking about milliwatt, not Megawatt lasers.

Don't know, but we lost three telescopes last week.
