Can you imagine? The Edmund Fitzgerald just disappeared in front of you. Somehow you made it to safety behind the lee of White Fish point and they ask you to go back out…

...caused by the acceleration of the engine to an abnormally high fan speed which initiated a multiwave, vibratory resonance... reasons for the acceleration and the onset of the destructive vibration could not be determined conclusively."

I see the J79 & B-58 as being made for each other, even though it might not look as so, when considering that the XJ79 first ran on 8 June 1954, and the XB-58 first flew on 11 November 1956. But the J79 was indeed meant to be, since inception, the B-58's engine.

I first started mapping GPS jamming in case it was an early warning of the Russian invasion of Ukraine. I hope it's not a sign of some mad Trumpian attack on Venezuela.

PIT's "petal tunnel" by Luis Vidal emulates something of the experience of emerging from Pittsburgh's Fort Pitt Tunnel.

β€œYou come out of the tunnel and, suddenly, you read the entire space. Everything’s there, visible and legible at one glance and that’s part of the beauty of this transformation.”

As you can imagine, clear communication at an airport is critically important. For example, even a colon can drastically change the meaning of a sentence.

'A pilot ate a Flight Attendant's sandwich.'

Today in 1962 at 4:00 AM PDT, as the Cuban Missile Crisis was entering its most dangerous phase, the Air Force test launched an Atlas D ICBM from Vandenberg Air Force Base, California, as US military forces worldwide were at DEFCON 3 and forces under the Strategic Air Command were at DEFCON 2.

Boeing sees no new single aisle plane untilΒ 2040 Subscription Required By Scott Hamilton Oct. 27, 2025, Β© Leeham News: Recent reports that Boeing is working on a new single-aisle aircraft to replace the 737 MAX and a New Midmarket Airplane (NMA), or a version of it, are fundamentally true but vastly overhyped. At a conference in Prague earlier this month, Boeing's Darren Hulst put a damper on this speculation, but said only that Boeing was "not close" to launching a new airplane.

Fact: The Airbus A220 was the company's first ever passenger glider. Commercially successful, it dominated the market for very, very short flights. Its short haul distance depended entirely on how strong the elastic bands were at launch.
