Koby Regalado, a student who witnessed the Tanay incident, said the bus slid down a downward slope and rammed head on to a military vehicle on exhibit where he and other students were taking pictures.

He said some 20 students were already on board the bus when it slid down towards the exhibit.

“Narinig po namin na may umaandar, pero sobrang bilis po. Paglingon ko, nakita ko na lang po si Pamela na naipit sa gitna nung bus at nung isa pong sasakyan ng sundalo,” Regalado said in a separate phone interview.

He added that he saw the bus driver chasing the vehicle to try to stop it from going down the slope, but the incident happened in a matter of seconds.
At the end of the day, we are leaving our sons and daughters to the limited hands of a teachers and tour guide and bus drivers sa field trip.

Ang kwento, its an inclined road, iniwan ng driver na bukas ang makina para lagyan ng tubig ang radiator, nung biglang umabante ang bus at tinumbok ang mga studyante, although may kalso eh di kinaya ng kalso pigilan ang bus.

This incident is screaming of stupidity at kapabayaan ng driver. Unang una, sa driving school (which im sure di dinaanan ng bus driver) itinuturo na itutok mo ang gulong mo sa sidewalk kung inclined ang parking. 2nd handbrake. At walang kwenta kalso kung bus dala mo at pasulong ang kalye.
