Hilo International PHTO → Ellison Onizuka Kona International PHKO

While I'm still figuring out where my next multi-leg journey will take me, I thought: why not see if the Cessna 172 can fly over Mauna Kea? Its service ceiling is 14,000 ft, and Mauna Kea stands at 13,803 ft.

So, I packed some oxygen and took off. After a wide circle around the volcano and the slowest climb of all time (100–200 ft/min), the altimeter maxed out at 15,000 ft, leaving me with a comfortable margin over the summit.

35 years ago today a particularly long total #SolarEclipse hit Hawaii and Central and South America - of which astronomers on #MaunaKea made ample use as the legendary #WGBH documentary "Eclipse of th Century" shows: https://www.youtube.com/watch?v=JRI5FEQbn7o = https://archive.org/details/EclipseoftheCentury (my favorite scene is in minute 45-46 when astronomers rush out of a telescope control room during totality to marvel at the eclipse with their own eyes). See also https://diary4dan.wordpress.com/2016/07/11/heute-vor-25-jahren-bei-der-riesen-sofi-in-mexiko and https://skyweek.wordpress.com/2026/07/06/das-sind-die-asteroiden-torifune-kamo%ca%bboalewa ("Eine ungewöhnlich lange Totale Sonnenfinsternis") for further memories of that event I've found online 10 years ago and today.

Mauna Kea summit at sunset. Observatories lining the ridge, clouds far below, and a sky cycling through every shade of orange before it’s done.

There’s always another view waiting somewhere.
