Learning of Thursday’s safe emergency landing of an Air Canada jet in Honolulu came as a great relief to all, with even the seriously injured passengers apparently on the road to recovery.

It was that always-feared turbulence that caused the plane to plummet suddenly, with no time to heed a “fasten your seatbelts” warning. Those unbuckled flew out of their seats, enduring the pain and bruising from cabin impacts.

So next time your flight attendant says to keep seatbelts buckled midflight, don’t roll your eyes.

A big new screen at Aloha Stadium

Aloha Stadium may be old, but it can still wear some new bling: in this case, a larger, sharper electronic scoreboard. It won’t be like your big-screen TV at home. It’s bigger (74 feet by 20 feet). It’s more expensive ($800,000). And someone else is paying for it (IMG College LLC, the stadium’s new advertising rights holder).

It should have a good run. Even though Gov. David Ige approved funding this week to replace Aloha Stadium, the new $350 million edifice won’t open for at least, ahem, five years. The jumbo screen should be in place for the Aug. 17 Los Angeles Rams-Dallas Cowboys exhibition game.
