The aerially deployable position marking device of claim 1, includingsaid handle being secured to an upper portion of said housing. 6. The aerially deployable position marking device of claim 1, includingsaid locating element having a visibility enhancing portion. 7. The aerially deployable position marking device of claim 6, includingsaid visibility enhancing portion being at least one streamer structured to make said device more visible. 8. The aerially deployable position marking device of claim 1, includingsaid speed reducing element being a parachute. 9. The aerially deployable position marking device of claim 1, includingsaid locating element being electrically energized. 10. The aerially deployable position marking device of claim 9, includingsaid locating element being a light. 11. The aerially deployable position marking device of claim 9, includingsaid locating element being an acoustic element. 12. The aerially deployable position marking device of claim 9, includingsaid locating element being an RF signal source. 13. The aerially deployable position marking device of claim 1, includingan electrical switch secured to said housing. 14. The aerially deployable position marking device of claim 13, includingat least one battery operatively associated with said switch for energizing said electrically energized locating element. 15. The aerially deployable position marking device of claim 1, includingsaid device having an overall height of about 20 to 30 inch. 16. The aerially deployable position marking device of claim 1, includingsaid housing having a tubular metal body. 17. An aerially deployable position marking device comprising an elongated housing having an upper end and a lower end;a handle secured to said housing;a parachute secured to said housing or said handle to reduce the rate of descent of said device through the air;a ground engaging portion at or adjacent the lower end of said housing, said ground engaging portion having a projecting spike-like element; andat least one locating element, whereby said marking device will provide its marking function during descent, to a target area and upon striking the target area without requiring secondary action and whereby said spike-like element will enhance the likelihood of said device engaging the ground. 18. The aerially deployable position marking device according to claim 17, further comprising a weighted lower portion of said device having sufficient weight to facilitate said device being generally vertically oriented with said ground engaging portion oriented generally downwardly as said device travels through the air. 19. The aerially deployable p osition marking device according to claim 18, wherein said weighted lower portion includes a weighted element disposed above said ground engaging portion. 20. The aerially deployable position marking device of claim 17, wherein said handle is secured to an upper portion of said housing. 21. The aerially deployable position marking device of claim 17, wherein said locating element includes a visibility enhancing portion. 22. The aerially deployable position marking device of claim 17, wherein said visibility enhancing portion includes at least one streamer structured to make said device more visible. 23. The aerially deployable position marking device of claim 17, wherein said locating element is electrically energized. 24. The aerially deployable position marking device of claim 23, wherein said locating element is a light. 25. The aerially deployable position marking device of claim 23, wherein said locating element is an acoustic element. 26. The aerially deployable position marking device of claim 23, wherein said locating element is an RF signal source. 27. The aerially deployable position marking device of claim 23, including an electrical switch secured to said housing. 28. The aerially deployable position marking device of claim 27, including at least one battery operatively associated with said switch for energizing said electrically energized locating element. 29. The aerially deployable position marking device of claim 17, wherein said device has an overall height of about 20 to 30 inches. 30. The aerially deployable position marking device of claim 17, wherein said housing has a tubular metal body.
