Top 50 aerial navigation innovations

Flying magazine has compiled their list of the 50 most important aerial navigation innovations. I think that they missed an important one, the E6B flight computer.

Book Review – McDonnell Douglas/Boeing F-15 Baz

McDonnell Douglas/Boeing F-15 Baz (Aircraft of the Israeli Air Force 5)
Ra’anan Weiss
Alon Koren
IsraDecal Publications
2006

What it’s about:

The F-15 (but not the F-15I) in Israeli Defense Force service.

What I liked about the book:

Excellent photographs
Extensive history of the F-15 in Israeli service, with information that is found nowhere else
Color profiles of aircraft

What could have been done better:

Too many spelling errors and a mediocre translation into English
Some factual errors (the F-15 did not use the AIM-9H, and the Israelis did not use the CH-53E helicopter)

Summary:

The Israelis have been the most significant user of the F-15 aside from the USAF, making good use of it both as an air superiority fighter and a fighter-bomber. Given the secrecy around the Israeli Air Force, information about their use of the F-15 has been scarce. This book pulls back the covers on this subject. The book might have earned a five star rating, if not for its drawbacks which are relatively minor but annoying.

Rating:

4 stars out of a possible 5.

STS-134 ENDEAVOUR, ATV-2 JOHANNES KEPLER & ISS FROM TMA-20

STS-134 ENDEAVOUR, ATV-2 JOHANNES KEPLER & ISS FROM TMA-20

May 23, 2011:
Shortly after undocking the TMA-20 Soyuz spacecraft “Varangian” from the ISS’s Rassvet module; Expedition 27 astronaut Paolo Nespoli (ESA), from a distance of about 200 meters snaps these incredible images as well as video of the International Space Station (ISS), Space Shuttle Endeavour and ESA’s ATV-2.
STS-134 Space Shuttle Endeavour was docked to the Harmony module for OV-105’s final mission (ULF6). Opposite the shuttle, ESA’s Automated Transfer Vehicle-2 (ATV-2) “Johannes Kepler” cargo spacecraft can be seen docked to the Zvezda module. The entire shoot lasted approximately 30 minutes and during the shoot the ISS executed a 130 degree maneuver to change the angle of the images.

Onboard TMA-20 was Expedition 27 Commander; cosmonaut Dmitry Kondratyev, ESA astronaut Paolo Nespoli and NASA astronaut Cady Coleman.

The infamous Goddard editorial in the New York Times

That Professor Goddard, with his “chair” in Clark College and the countenancing of the Smithsonian Institution, does not know the relation of action and reaction, and of the need to have something better than a vacuum against which to react—to say that would be absurd. Of course he only seems to lack the knowledge ladled out daily in high schools.

The New York Times, January 13, 1920

 

Further investigation and experimentation have confirmed the findings of Isaac Newton in the 17th Century and it is now definitely established that a rocket can function in a vacuum as well as in an atmosphere. The Times regrets the error.

The New York Times, July 17, 1969 (perhaps coincidently, the day after Apollo 11 was launched)
