  • Was the moisture level on that day conducive for curing?
  • What is the difference between carbon fiber, Kevlar and glass?
  • The cleanest airframes are Composite?
  • Did the exact proportions get mixed?
  • What about lightning with composites or all metal airframes?
  • When is it ok to use Automobile or Mogas as opposed to Aviation or Avgas?

Peter Hill (1928 to 1989) was a tour operator working out of Shaumburg, IL. On June 14, 1985 Peter's tour of approximately 40 was aboard TWA flight 847 when it was high jacked shortly after leaving Athens. Son Paul Hill became somewhat of a national icon then promoting the release of the hostages taken by the Shi'ite Muslims. Paul appeared on the 11pm news with Dan Rather , Good Morning America and several TV spots local to West Palm Beach, FL. Paul was often seen being interviewed from home and the station by Gary Tuckman now with CNN. Paul was also on the front page of the Daily News and stood next to Senator Monahan as he greeted his father disembarking from the Air force C130 in Wiesbaden, Germany when the hostages were released.

Peter Hill - labeled by Life Magazine "The TWA hostage who fought back" April 1986 edition - having been to the mid east over 100 times, was very knowledgeable and outspoken about the event. He appeared on several talk shows including Charlie Rose. Life and Time magazine did feature articles on Peter showing photos he took secretly while a captive for 14 days.

Victor Carbonara (1989 to 1976) was president of Kollsman Instruments, Inc while the company resided in Elmhurst, Queens, NY. Among Mr. Carbonara's 43 patients was the Kollsman window. The kollsman window is known to all pilots as the window that adjusts the altimeter to the outside air pressure. It is still in use today.

On May 20, 1927, Charles Lindbergh took off from Roosevelt Field in New York with Carbonara's periscope Sextant.The next day Lindbergh landed at Le Bourget Field, near Paris. Later Anne Lindbergh used Carbonara maping tools to chart routes to China.

Aviation Periscope Sexton
Invented by: Victor Carbonara

This was made after Victor Carbonara filed his patent application in 1931 and before the patent was issued in August 1934. It is identical to the original Model 342, but here the eyepiece rotates around a vertical axis so that sights can easily be taken in any direction. The U.S. Naval Observatory transferred it to the Smithsonian in 1948.
