Hey @SouthwestAir I just got done being held against my will for over 2 hours along with one hundred something other passengers on #flight6263 and no apology given or explanation for being held! pic.twitter.com/CC2slLpayk — Sean Michael (@Sean_Sells) May 7, 2018

Southwest Flight 6263 was arriving from Fort Lauderdale, Florida, a little after 1:30 a.m. when the accident happened.

In a statement from Southwest Airlines, the company said “a ground vehicle came into contact with the aircraft.”

Southwest said no one on board the plane was injured, although several passengers took to Twitter to complain about the delays caused by the crash.

We’re so sorry for the trouble tonight in Baltimore. We appreciate your patience, and our Team will do everything they can to get you all on your way as soon as possible. -Rebekah — Southwest Airlines (@SouthwestAir) May 7, 2018

There is no word yet about whether the person in the truck was injured.

In a statement, Southwest said it is conducting an internal investigation to figure out what happened but it would be “irresponsible to provide details until we’ve had time to thoroughly review the facts.”

This is a developing story.
