In order to contribute to the analysis of such cases, however, scientists would wish to have available evidence of a variety of types, certainly including narrative accounts, but also involving more concrete information such as radar records, tape recordings, etc. For further information about vehicle interference cases, see Section 15. Pilots are highly motivated, yet do not over-react during stressful situations. Pilots can change their flight path so as to see the ground behind the object and thereby establish a maximum slant range to it. Pilots can use their radio to contact ground support for further information or assistance.
Aircraft have a wide variety of instruments that react differently to electromagnetic radiation.
Nevertheless, according to Haines, even an experienced pilot can be deceived by some of the unusual phenomena listed in Appendix 3. The largest category of effects is airborne radar contact, while the second largest category is radio interference or complete but temporary radio failure. The entire sky was dark and clear ahead and above the airplane, except for a partial undercast with small clouds extending to about 20 miles ahead. The aircraft was just south of Syracuse, New York. Suddenly and unexpectedly, the airplane began to turn to the left, making a 15 degree bank.
