發現了那架波音 737 Max 9 在飛行中掉落的門塞的波特蘭科學老師Bob Sauer認為他後院的樹木可能幫助保存了證據，“樹木像安全氣囊一樣阻止墜落，所以它沒有猛烈撞擊地麵。”

The Porland science teacher Bob Sauer，who found the door plug that blew out of Boeing Max 9 during the flight thought his trees in his backyard might help save the data，“The trees acted like an airbag and made for a longer fall and a lower force，so the door was not damaged by the fall. ”
