High Energy field, different time/space, and unstable aircraft

We already know that the island is always moving and appears to have time traveling capabilities.

It's possible that the aircrafts cannot stably cross the time/space barrier.

List of aircraft that have crashed on the island:

• Oceanic 815
• Drug smugglers' plane
• The first freighter helicopter (Naomi's helicopter)

List of aircraft that landed successfully on the island:

• Ajira Airways Flight 316
• Second freighter helicopter
• Multiple supply airdrops

Oceanic 815

On September 22, 2004, Desmond failed to enter the numbers into the computer which resulted in an electromagnetic buildup and subsequent release of a huge amount of energy. Although he was able to reset the countdown the energy was enough to pull the Oceanic 815 toward the island and apparently break it up.

Ajira Airways Flight 316

In 2007 the Oceanic 6 bordered Ajira Airways Flight 316. This plane during its course encountered huge turbulence during the night. The plane started to shake hard and bright beam of white light engulfed the whole cabin. Immediately after the flash of light, the pilots found themselves in daylight, although the plane was traveling at night. (time/space travel?)

Drug smugglers' plane

The drug smugglers' plane is a destroyed Beechcraft 18 airplane that crashed on the Island after April in 2001. t carried on board a Nigerian drug smuggler disguised as a priest, the body of a real priest and heroin hidden inside of Virgin Mary statues. It also had an on-board radio and maps of Nigeria.
