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)

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)


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.

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.
